MAX4781/MAX4782/MAX4783 19-2522 Rev 3 2/05 High-Speed, Low-Voltage, 0.7 CMOS Analog Switches/Multiplexers General Description Features On-Resistance The MAX4781/MAX4782/MAX4783 are high-speed, 0.7 (+3V Supply) low-voltage, low on-resistance, CMOS analog multiplex- 1.6 (+1.8V Supply) ers/switches configured as an 8-channel multiplexer (MAX4781), two 4-channel multiplexers (MAX4782), On-Resistance Match Between Channels and three single-pole/double-throw (SPDT) switches 0.3 (+3V Supply) (MAX4783). On-Resistance Flatness These devices operate with a +1.6V to +3.6V single 0.1 (+3V Supply) supply. When powered from a +3V supply, MAX4781/ Single-Supply Operation Down to 1.6V MAX4782/MAX4783 feature a 0.7 on-resistance High-Current Handling Capacity (150mA (R ), with 0.3 R matching between channels, and ON ON Continuous) 0.1 R flatness. These devices handle rail-to-rail ON +1.8V CMOS-Logic Compatible analog signals while consuming less than 3W of qui- escent power. They are available in space-saving 16- Fast Switching Times: t = 11ns, t = 4ns ON OFF pin thin QFN (3mm x 3mm) and TSSOP packages.

Limit forward-diode current to CC 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.
