The ADM3483E / ADM3486E / ADM3488E / ADM3490E / ADM3491E are 3.3 V low power data transceivers with ±15 kV ESD protection suitable for full andhalf-duplex communication on multipoint bus transmission lines. They are designed for balanced data transmission and comply with TIA/EIA standards RS-485 and RS-422. The ADM3483E / ADM3486E is a half-duplex transceiver that shares differential lines and has separate enable inputs for the driver and receiver. The full-duplex ADM3488E / ADM3490E / ADM3491E transceivers have dedicated differential line driver outputs and receiver inputs. The ADM3491E also features enable inputs for the driver and receiver.The devices have a 12 kΩ receiver input impedance which allows up to 32 transceivers on a bus. Since only one driver should be enabled at any time, the output of a disabled or powered down driver is three-stated to avoid overloading the bus. The driver outputs of the ADM3483E / ADM3486E / ADM3488E are slew rate limited in order to reduce EMI and data errors caused by reflections from improperly terminated buses. The receiver has a failsafe feature which ensures a logic high output when the inputs are floating. Excessive power dissipation caused by bus contention or by output shorting is prevented with a thermal shutdown circuit. The parts are fully specified over the industrialtemperature ranges and are available in narrow 8-lead and 14-lead (ADM3491E) SOIC packages.

The ADM560 / ADM561 are four driver/five receiver interface devices designed to meet the EIA-232 standard while operating with a single +3.3 V power supply. The devices feature an on-board dc-to-dc converter, eliminating the need for dual ±5 V power supplies. This dc-dc converter contains a voltage doubler and voltage inverter which internally generates ±6.6 V from the input +3.3 V power supply.The ADM560 and ADM561 consume only 5 mW making them ideally suited for battery and other power-sensitive applications. A shutdown facility is also provided which reduces the power to 0.66 µW.The ADM560 contains active low shutdown and active high receiver enable signals. In shutdown mode, two receivers remain active thereby allowing monitoring of peripheral devices. This feature allows the device to be shut down until a peripheral device begins communication. The active receivers can alert the processor which can then take the ADM560 out of the shutdown mode.The ADM561 features active high shutdown and an active low receiver enable. In this device all receivers are disabled in shutdown.The ADM560 / ADM561 is fabricated using CMOS technology for minimal power consumption. It features a high level of over-voltage protection and latch-up immunity. The receiver inputs can withstand up to ±25 V levels. The transmitter inputs can be driven from either 3V or 5V logic levels. This allows operation in mixed 3 V/5 V power supply systems.The ADM560 / ADM561 is packaged in a 28-pin SO and a 28-pin SSOP package.APPLICATIONS Notebook computers Peripherals Modems Printers Battery-operated equipment

The MAX3188E/MAX3189E single RS-232 transmitters in a SOT23-6 package are for space- and cost-constrained applications requiring minimal RS-232 communications. These devices consume only 150µA of supply current from ±4.5V to ±6V supplies. They feature a shutdown input that reduces current consumption to only 1µA and forces the transmitter output into a high-impedance state. RS-232 data transmission is guaranteed up to 250kbps with the MAX3188E and up to 1Mbps with the MAX3189E.The MAX3188E/MAX3189E are EIA/TIA-232 transmitters that convert CMOS/TTL logic levels to RS-232-compliant signals. The transmitter output is protected to ±15kV using the IEC 1000-4-2 Air-Gap Discharge method, to ±8kV using the IEC 1000-4-2 Contact Discharge method, and to ±15kV per the Human Body Model, ensuring strict compliance with international standards. The MAX3188E/MAX3189E transmitters have a standard inverting output.ApplicationsDiagnostic PortsDigital Still CamerasHandheld EquipmentNetwork EquipmentSet-Top BoxesTelecommunications

The AD8016 is a 2nd generation DSL line driver capable of delivering full rate ADSL from the Central Office on a cool 1.5 W total power dissipation.With the addition of a flexible Standby functionality, and packaged in a 20-Lead PSOP, a 24-Lead SOIC, and a 28-Lead TSSOP package, the AD8016 is optimized for DSL line driving at both ends of the line. Novel circuit design and a new ±12 V, high speed bipolar process enable each amplifier in the dual AD8016 to deliver 20 V pk-to-pk output voltage and more than 400 mA typical output current.The combination of a breakthrough in two stage current gain and high speed bipolar process technology means that the AD8016 can deliver low distortion output voltages to within 2 V of the power supply rail, setting the standard in high efficiency.

The MAX9205/MAX9207 serializers transform 10-bit-wide parallel LVCMOS/LVTTL data into a serial high-speed bus low-voltage differential signaling (LVDS) data stream. The serializers typically pair with deserializers like the MAX9206/MAX9208, which receive the serial output and transform it back to 10-bit-wide parallel data.The MAX9205/MAX9207 transmit serial data at speeds up to 400Mbps and 660Mbps, respectively, over PCB traces or twisted-pair cables. Since the clock is recovered from the serial data stream, clock-to-data and data-to-data skew that would be present with a parallel bus are eliminated.The serializers require no external components and few control signals. The input data strobe edge is selected by TCLK_R/F. Active-low PWRDN is used to save power when the devices are not in use. Upon power-up, a synchronization mode is activated, which is controlled by two SYNC inputs, SYNC1 and SYNC2.The MAX9205 can lock to a 16MHz to 40MHz system clock, while the MAX9207 can lock to a 40MHz to 66MHz system clock. The serializer output is held in high impedance until the device is fully locked to the local system clock, or when the device is in power-down mode.Both the devices operate from a single +3.3V supply, are specified for operation from -40°C to +85°C, and are available in 28-pin SSOP packages.ApplicationsAdd/Drop MultiplexersBackplane and Interconnect ApplicationsCell Phone Base Stations Digital Cross-ConnectsDSLAMNetwork Routers and Switches
