NLAS9431
Low Voltage Single Supply
Dual DPDT Analog Switch
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 V
lower and more linear over input voltage than R
analog switches.
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.
demultiplexer analog switch with two Select pins that each controls
