MAX4781/MAX4782/MAX4783
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 0.7 Ω on-resistance (RON), with 0.3Ω RON matching between channels, and 0.1Ω RON flatness. These devices handle rail-to-rail analog signals while consuming less than 3µW of quiescent power. They are available in space-saving 16pin thin QFN (3mm x 3mm) and TSSOP packages.

Note 1: Signals on X, Y, Z, X_, Y_, and Z_ exceeding VCC or GND are clamped by internal diodes. Limit forward-diode current to maximum current rating.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
