The MAX4991–MAX4994 low on-resistance analog switches operate from a single +1.8V to +5.5V supply. The MAX4991/MAX4993 feature a slow turn-on time to reduce clicks and pops due to coupling capacitors and audio amplifiers with a DC output bias. This feature provides click-and-pop reduction without adding additional parts for existing architectures.The MAX4991/MAX4992 are dual single-pole/double-throw (SPDT) switches, while the MAX4993/MAX4994 are double-pole/double-throw (DPDT) switches. The MAX4993/MAX4994 feature an active-low enable input (active-low EN) that sets all the channels to high impedance and reduces supply current when driven high. These devices have 0.3Ω on-resistance and 0.004% THD+N to route high fidelity audio signals.The MAX4991–MAX4994 are available in space-saving 10-pin UTQFN (1.4mm x 1.8mm) package, and are specified for operation over the -40°C to +85°C extended temperature range.ApplicationsAudio Signal RoutingCellular PhonesPortable MP3 PlayersSpeaker Headset Source Switching

The MAX7356/MAX7357/MAX7358 8-channel I²C switches/multiplexers expand the main I²C bus to any combination of 8 extended I²C buses. They enable a master on the main bus to isolate and communicate with devices or groups of devices that may otherwise have slave address conflicts. Any extended bus can be connected or disconnected by control packets from the main I²C bus writing to the main control register of these I²C switches.The MAX7357 and MAX7358 feature an enhanced mode that includes a built-in timer used to monitor all extended buses for lock-up conditions. If the clock or data line of any of these buses is low for more than 25ms (typ), a lock condition is detected. An optional interrupt can be generated through the bidirectional active-low RST/active-low INT. The master can read the bus lock-up register to find out which extended bus is locked up. The master can also enable the MAX7357 or the MAX7358 to send a 'flush-out' sequence on the faulty channel. There is an optional preconnection check that can be enabled to toggle the extended bus clock and data line low then high to ensure the downstream bus is not locked high prior to connecting it to the host bus.The MAX7356/MAX7357/MAX7358 are transparent to signals sent and received at each channel, allowing multiple masters. Any device connected to an I²C bus can transmit and receive signals; however, only the master connected to the host side of the MAX7356/MAX7357/MAX7358 should address the device.The MAX7356/MAX7357/MAX7358 are available in 24-pin TSSOP and TQFN packages and are specified over the extended -40°C to +85°C temperature range.ApplicationsBase StationsControl and Automation DevicesNetworking EquipmentRAIDServersSFP Control Interface

The MAX4996/MAX4996L triple DPDT analog switches operate from a single +2.5V to +5.5V supply, and feature 2.0Ω (typ) on resistance, low 6pF (typ) on-capacitance, and low power-supply current consumption. The MAX4996/MAX4996L combine the low capacitance and low resistance necessary for high-frequency switching applications in portable electronics.The MAX4996/MAX4996L have three logic inputs to control the switches in pairs. The MAX4996 has an active-high enable input (EN) to disable the switches, while the MAX4996L has an active-low enable input (active-low EN) to disable the switches. The enable input decreases the supply current and also places the COM_ outputs in a high-impedance state.The MAX4996/MAX4996L feature a 5µA (max) supply-current consumption when the logic inputs are not rail-to-rail. This feature is especially valuable in applications where direct interface to low-voltage processors is necessary.The MAX4996/MAX4996L are available in a space-saving 24-pin (3.5mm x 3.5mm) TQFN package and operate over the -40°C to +85°C temperature range.ApplicationsCell PhonesGPSPDAsPersonal Media Players (PMP)SD Card SwitchingUART Signal SwitchingUSB Signal Switching

The MAX4968B/MAX4968C are 16-channel, high-linearity, high-voltage (HV), bidirectional SPST analog switches with 18Ω (typ) on-resistance. The devices are ideal for use in applications requiring high-voltage switching controlled by a low-voltage control signal, such as ultrasound imaging and industrial printing. The MAX4968C provides integrated 40kΩ bleed resistors on each switch terminal to discharge capacitive loads. Using HVCMOS technology, these switches combine high-voltage bilateral MOS switches and low-power CMOS logic to provide efficient control of high-voltage analog signals.In typical ultrasound applications, the MAX4968B/MAX4968C do not require a dedicated HV supply, which implies a significant simplification of system requirements. The negative voltage supply can be shared with the transmitter and the positive voltage supply is typically +12V.The devices are available in a 64-bump BGA package and are specified over the -40°C to +85°C extended temperature range.ApplicationsIndustrial PrintingMedical Ultrasound ImagingNondestructive Testing (NDT)
