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.

±15kV ESD-Protected, Low-Voltage, CMOS Analog Multiplexers/Switches The MAX4558/MAX4559/MAX4560 are ESD protected (per IEC 1000-4-2) at their X, Y, Z output pins and X_, Y_, Z_ input pins. These ICs feature on-chip bidirectional silicon-controlled rectifiers (SCRs) between the protected pins and GND. The SCRs are normally off and have a negligible effect on the switches’ performance.
