General Description

The MAX4558/MAX4559/MAX4560 are low-voltage, CMOS analog ICs configured as an 8-to-1 multiplexer (MAX4558), a dual 4-to-1 multiplexer (MAX4559), and a triple single-pole/double-throw (SPDT) switch (MAX4560). Each switch is protected against ±15kV electrostatic discharge (ESD) shocks, without latchup or damage.

These CMOS devices can operate continuously from dual supplies of ±2V to ±6V or from 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 10nA at +85°C max.

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