... General Description The MAX4781/MAX4782/MAX4783 are high-speed, low-voltage, low on-resistance, CMOS analog multiplex- ers/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 ...

... V and GND power the internal logic and set the input CC logic limits. Logic inputs have ESD-protection diodes to ground. The MAX4781/MAX4782/MAX4783 operate from a sin- gle supply between +1.6V and +3.6V. Switch on-resis- tance increases as the supply voltage is lowered. 8 _______________________________________________________________________________________ In 50Ω systems, signal response is reasonably flat up to 50MHz (see the Typical Operating Characteristics) ...
