NLAS9431 D

NLAS9431
Low Voltage Single Supply
Dual DPDT Analog Switch
The NLAS9431 is an advanced dual−independent CMOS double
pole−double throw (DPDT) 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 VCC to GND).
The device has been designed so the ON resistance (RON) is much
lower and more linear over input voltage than RON of typical CMOS
analog switches.
The channel select input is compatible with standard CMOS outputs.
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 NLAS9431 can also be used as a quad 2−to−1 multiplexer−
demultiplexer analog switch with two Select pins that each controls
two multiplexer−demultiplexers.
