The NLAS9431 ia an advanced CMOS double pole-double throw (DPDT) analog switch fabricated with silicon gate CMOS technology. It achieves hgih speed propagation delays and low ON resistance while maintaining CMOS low power dissipation.This DPDT controls analog and digital voltages that may vary across the full power-supply range from VCCto GND.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.
