The MAX4781/MAX4782/MAX4783 are high-speed, low-voltage, low on-resistance, CMOS analog multiplexers/switches configured as an 8-channel multiplexer (MAX4781), two 4-channel multiplexers (MAX4782), and three single-pole/double-throw (SPDT) switches (MAX4783).These devices operate with a +1.6V to +3.6V single supply. When powered from a +3V supply, MAX4781/MAX4782/MAX4783 feature a 0.7Ω on-resistance (RON), with 0.3Ω RONmatching between channels, and 0.1Ω RONflatness. These devices handle rail-to-rail analog signals while consuming less than 3µW of quiescent power. They are available in space-saving 16-pin thin QFN (3mm x 3mm) and TSSOP packages.ApplicationsAudio Signal RoutingBattery-Operated EquipmentCommunications CircuitsLow-Voltage Data-Acquisition Systems

The MAX4780/MAX4784 are low on-resistance, low-voltage, quad 2:1 analog multiplexers that operate from a single +1.6V to +4.2V supply. These devices have fast switching speeds (tON= 20ns, tOFF= 8ns), handle rail-to-rail analog signals, and consume less than 1µW of quiescent power.When powered from a +2.7V supply, the MAX4780/MAX4784 feature low 0.7Ω on-resistance (RON), and 0.1Ω RONflatness. The digital logic input is +1.8V CMOS-logic compatible when using a single +3V supply. The MAX4780/MAX4784 are available in 16-pin TSSOP and 3mm x 3mm thin QFN packages.ApplicationsAudio/Video Signal RoutingBattery-Powered SystemsCell PhonesCommunications CircuitsHard DrivesLow-Voltage Data-Acquisition SystemsModemsPCMCIA CardsPower Routing

The MAX4785-MAX4788 family of switches feature internal current limiting to prevent host devices from being damaged due to faulty load conditions. These analog switches have a low 0.7Ω on-resistance and operate from a 2.3V to 5.5V input voltage range. They are available with guaranteed 50mA and 100mA current limits, making them ideal for load-switching applications.When the switch is on and a load is connected to the port, a guaranteed blanking time of 14ms ensures that the transient voltages settle down. If after this blanking time the load current is greater than the current limit, the MAX4785 and MAX4787 enter a latch-off state where the switch is turned off and active-low FLAG is issued to the microprocessor. The switch can be turned on again by cycling the power or the ON pin.The MAX4786 and MAX4788 have an autoretry feature where the switch turns off after the blanking time and then continuously checks to see if the overload condition is present. The switch remains on after the overload condition disappears.The MAX4785 and MAX4787 are available in a tiny space-saving 4-pin or 5-pin SC70 package. The MAX4786 and MAX4788 are available only in the 4-pin SC70 package. For higher current current-limiting switches, refer to the MAX4789-MAX4794 and MAX1693 data sheets.ApplicationsCell PhonesGlobal Positioning Systems (GPS)Handheld DevicesPDAs and Palmtop Devices
