MAX4582 Active: In Production.
MAX4583 Active: In Production.


The MAX4581/MAX4582/MAX4583 are low-voltage, CMOS analog ICs configured as an 8-channel multiplexer (MAX4581), two 4-channel multiplexers (MAX4582), and three single-pole/double-throw (SPDT) switches (MAX4583).

These CMOS devices can operate continuously with ±2V to ±6V dual power supplies or a +2V to +12V single supply. Each switch can handle rail-to-rail analog signals. The off-leakage current is only 1nA at +25°C or 5nA at +85°C.

All digital inputs have 0.8V to 2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a single +5V or dual ±5V supplies.
