±15kV ESD-Protected, Low-Voltage, CMOS
Analog Multiplexers/Switches
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 sin-
gle supply. Each switch can handle Rail-to-Rail
®
ana-
log 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.
