Part details & applications

The MAX4581L/MAX4582L/MAX4583L are low-voltage, CMOS analog ICs configured as an 8-channel multiplexer (MAX4581L), two 4-channel multiplexers (MAX4582L), and three single-pole/double-throw (SPDT) switches (MAX4583L).

These CMOS devices operate with a +2V to +12V single supply. Each switch can handle rail-to-rail analog signals. Off-leakage current is only 2nA at +25°C.

All digital inputs have 0.8V to 2.0V logic thresholds to ensure TTL/CMOS-logic compatibility when using a +12V supply.

Applications

Audio/Video Signal Routing
Communications Circuits
