The MAX4740/MAX4740H low on-resistance (0.61Ω typ) analog switches operate from a single 1.6V to 5.5V supply. The MAX4740/MAX4740H are quad, single-pole, double-throw (SPDT) switches and are configured to route audio signals. The MAX4740/MAX4740H are pin-to-pin compatible parts with the ST Microelectronics quad SPDT STG3699 analog switch.The MAX4740 is a quad SPDT switch and the MAX4740H is a quad SPDT switch that can be placed in a high-impedance mode. Switching logic is controlled by 2 control bits (CB1 and CB2). The MAX4740/MAX4740H also feature a low on-resistance match (0.06Ω) and low power-supply current (0.3µA), which increases battery life.The MAX4740/MAX4740H are available in a tiny 3mm x 3mm, 16-pin TQFN-EP, and 2.5mm x 2.5mm, 16-pin ultra-thin QFN packages.ApplicationsCellular PhonesNotebook ComputersPDAs and Other Handheld Devices

The MAX4744/MAX4744H/MAX4745/MAX4745H/MAX4746H dual SPDT (single-pole/double-throw) audioswitches feature negative signal capability that allowssignals as low as VCC - 5.5V to pass through withoutdistortion. These analog switches have a low on-resistanceand low supply current, and operate from a single+1.8V to +5.5V supply.The MAX4744/MAX4744H have internal shunt resistorsthat automatically discharge the capacitance at the normallyopen (NO) and normally closed (NC) terminalswhen they are not connected. The MAX4746H featuresinternal shunt resistors on NC_ terminals. This reducesclick-and-pop sounds that occur when switching audiosignals between precharged points. A break-before-makefeature further reduces popping. The MAX4744/MAX4745 control the switches with two control bits CB1 and CB2. The MAX4744H/MAX4745H/MAX4746H haveone control bit to switch both switches and an enableinput active-low EN to put the switches in a high-impedance mode.The MAX4744H/MAX4745H/MAX4746H also have aninternal protection network against voltages applied toCOM_ when VCC = 0V.These devices are available in a space-saving 10-pinµDFN (2mm x 2mm) package and operate over the-40°C to +85°C extended temperature range.ApplicationsCellular PhonesMP3 PlayersNotebook ComputersPDAs and Other Handheld DevicesPower RoutingSpeaker Switching

The MAX7367/MAX7368/MAX7369 bidirectional, four-channel I²C switches/multiplexer expand the main I²C bus up to four extended buses. The MAX7369 1:4 multiplexer connects the main I²C bus to one channelat a time. The MAX7367/MAX7368 four-channel switches connect the main I²C bus to one or more channels at a time.These devices isolate bus loading by extending the I²C bus onto different channels. The MAX7367/MAX7368/MAX7369 allow more devices to be interconnected to a master controller and multiple devices with the same I²C address to communicate to a master. The channels are selected through the main I²C bus by writing to the internal control register of the device.Any device connected to an I²C bus can transmit and receive signals. The MAX7367/MAX7368/MAX7369 are transparent to signals sent and received at each channel, allowing multiple masters. These devices are compatible with the I²C protocol of clock stretch, synchronization, and arbitration in case multiple masters address the bus at the same time.All devices are set to the default state during initial power-up. The MAX7367/MAX7368 have an active-low RESET input allowing external circuitry to set the MAX7367/MAX7368 to its default state anytime after the device has powered up. The MAX7367/MAX7369 have interrupt inputs, allowing devices on the extended bus to send an interrupt signal to the master on the main bus.The MAX7367/MAX7369 are available in 20-pin TSSOP packages, and the MAX7368 is available in a 16-pin TSSOP package. All devices operate over the -40°C to+85°C extended temperature range.ApplicationsBase StationsCellular PhonesMultimedia ElectronicsPCsRAIDSAN/NASServers
