NLAST9431
Low Voltage Single Supply
Dual DPDT Analog Switch
The NLAST9431 is an advanced CMOS dual−independent DPDT
(double pole−double throw) analog switch, fabricated with silicon
gate CMOS technology. It achieves high−speed propagation delays
and low ON resistances while maintaining CMOS low−power
dissipation. This DPDT controls analog and digital voltages that may

vary across the full power−supply range (from V to GND).

The channel−select input structure provides protection when
voltages between 0 V and 5.5 V are applied, regardless of the supply
voltage. This input structure helps prevent device destruction caused
by supply voltage − input/output voltage mismatch, battery backup,
hot insertion, etc.

The NLAST9431 can also be used as a quad 2−to−1 multiplexer−
demultiplexer analog switch with two Select pins that each controls
two multiplexer−demultiplexers.
