NLAS44599
Low Voltage Single Supply
Dual DPDT Analog Switch
The NLAS44599 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

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.
