The MAX7325 2-wire serial-interfaced peripheral features 16 I/O ports. Ports are divided into eight push-pull outputs and eight I/Os with selectable internal pullups and transition detection. Eight ports are push-pull outputs and eight I/Os may be used as a logic input or an open-drain output. Ports are overvoltage protected to +6V.All I/O ports configured as inputs are continuously monitored for state changes (transition detection). State changes are indicated by the active-low INT output. The interrupt is latched, allowing detection of transient changes. When the MAX7325 is subsequently accessed through the serial interface, any pending interrupt is cleared. The open-drain outputs are rated to sink 20mA, and are capable of driving LEDs. The active-low RST input clears the serial interface, terminating any I2C communication to or from the MAX7325.The MAX7325 uses two address inputs with four-level logic to allow 16 I2C slave addresses. The slave address also determines the power-up logic state for the I/O ports, and enables or disables internal 40kΩ pullups in groups of four ports.The MAX7325 is one device in a family of pin-compatible port expanders with a choice of input ports, open-drain I/O ports, and push-pull output ports (see Table 1 of the full data sheet).The MAX7325 is available in 24-pin QSOP and TQFN packages and is specified over the -40°C to +125°C automotive temperature range.ApplicationsAutomotiveCell PhonesNotebooksSAN/NASSatellite RadioServers

The MAX9247 digital video parallel-to-serial converter serializes 27 bits of parallel data into a serial-data stream. Eighteen bits of video data and 9 bits of control data are encoded and multiplexed onto the serial interface, reducing the serial-data rate. The data-enable input determines when the video or control data is serialized.The MAX9247 pairs with the MAX9248/MAX9250 deserializers to form a complete digital video serial link. Interconnect can be controlled-impedance PCB traces or twisted-pair cable. Proprietary data encoding reduces EMI and provides DC balance. DC balance allows AC-coupling, providing isolation between the transmitting and receiving ends of the interface. The LVDS output is internally terminated with 100Ω. For operating frequencies less than 35MHz, the MAX9247 can also pair with the MAX9218 deserializer.ESD tolerance is specified for ISO 10605 with ±10kV Contact Discharge and ±30kV Air-Gap Discharge.The MAX9247 operates from a +3.3V core supply and features a separate input supply for interfacing to 1.8V to 3.3V logic levels. This device is available in a 48-lead LQFP package and is specified from -40°C to +85°C or -40°C to +105°C.ApplicationsIn-Vehicle Entertainment SystemsLCDsNavigation System DisplaysVideo Cameras

The MAX1221/MAX1223/MAX1343 integrate a multichannel, 12-bit, analog-to-digital converter (ADC) and a 12-bit, digital-to-analog converter (DAC) in a single IC. The devices also include a temperature sensor and configurable general-purpose I/O ports (GPIOs) with a 25MHz SPI™-/QSPI™-/MICROWIRE™-compatible serial interface. The ADC is available in a 12 or an eight input-channel version. The DAC outputs settle within 2.0µs, and the ADC has a 225ksps conversion rate.All devices include an internal reference (2.5V) providing a well-regulated, low-noise reference for both the ADC and DAC. Programmable reference modes for the ADC and DAC allow the use of an internal reference, an external reference, or a combination of both. Features such as an internal ±1°C accurate temperature sensor, FIFO, scan modes, programmable internal or external clock modes, data averaging, and AutoShutdown™ allow users to minimize both power consumption and processor requirements. The low glitch energy (4nV•s) and low digital feedthrough (0.5nV•s) of the integrated DACs make these devices ideal for digital control of fast-response closed-loop systems.The devices are guaranteed to operate with a supply voltage from +2.7V to +5.25V. The devices consume 2.5mA at 225ksps throughput, only 22µA at 1ksps throughput, and under 0.2µA in the shutdown mode. The MAX1221/MAX1343 offer four GPIOs that can be configured as inputs or outputs.The MAX1221/MAX1223/MAX1343 are available in 36-pin thin QFN packages. All devices are specified over the -40°C to +85°C temperature range.ApplicationsClosed-Loop Controls for Optical Components and Base StationsData Acquisition SystemsSystem Supervision and Control

The MAX3421E USB peripheral/host controller contains the digital logic and analog circuitry necessary to implement a full-speed USB peripheral or a full-/low-speed host compliant to USB specification rev 2.0. A built-in transceiver features ±15kV ESD protection and programmable USB connect and disconnect. An internal serial interface engine (SIE) handles low-level USB protocol details such as error checking and bus retries. The MAX3421E operates using a register set accessed by an SPI interface that operates up to 26MHz. Any SPI master (microprocessor, ASIC, DSP, etc.) can add USB peripheral or host functionality using the simple 3- or 4-wire SPI interface.The MAX3421E makes the vast collection of USB peripherals available to any microprocessor, ASIC, or DSP when it operates as a USB host. For point-to-point solutions, for example, a USB keyboard or mouse interfaced to an embedded system, the firmware that operates the MAX3421E can be simple since only a targeted device is supported.Internal level translators allow the SPI interface to run at a system voltage between 1.4V and 3.6V. USB-timed operations are done inside the MAX3421E with interrupts provided at completion so an SPI master does not need timers to meet USB timing requirements. The MAX3421E includes eight general-purpose inputs and outputs so any microprocessor that uses I/O pins to implement the SPI interface can reclaim the I/O pins and gain additional ones.The MAX3421E operates over the extended -40°C to +85°C temperature range and is available in a 32-pin TQFP package (5mm x 5mm) and a 32-pin TQFN package (5mm x 5mm).

The MAX4885 integrates high-bandwidth analog switches and level translating buffers to implement a complete 1:2 or 2:1 multiplexer for VGA signals. The device provides switching for RGB, display data channel (DDC), and horizontal and vertical synchronization (HSYNC, VSYNC) signals. A low-noise charge pump with internal capacitors provides a boosted gate-drive voltage to improve performance of the RGB switches. In the 1:2 multiplexer mode, HSYNC/VSYNC inputs feature level-shifting buffers to support low voltage CMOS or standard TTL-compatible graphics controllers. In the 2:1 multiplexer mode, the output buffers for the HSYNC/VSYNC inputs are disabled, allowing bidirectional signaling. In both modes, DDC signals are voltage-clamped to an external voltage to provide level translation and protection. The MAX4885 features a 5µA shutdown mode and is ESD protected to ±8kV human body model (HBM) on externally routed pins.The MAX4885 is specified over the extended (-40°C to +85°C) temperature range, and is available in the 32-pin, 5mm x 5mm TQFN package.ApplicationsNotebook ComputersServers

The multiplexer output of the MAX180 is fed directly into the Analog-to-Digital Converter (ADC) input. The MAX181 brings out both the multiplexer output and ADC input to separate pins, allowing a programmable gain amplifier to be inserted between the MUX and the ADC.The systems allow the user to choose between an internal or an external reference. Furthermore, the internal reference value and the offest can be adjusted, allowing the overall system gain and offset errors to be nulled. The multiplexer has high impedence inputs, simplifying analog drive requirements.ApplicationsAutomated Test Equipment (ATE)Digital Signal Processing (DSP)High-Accuracy Process ControlHigh-Speed Servo Loops
