NLAST4599
Low Voltage Single Supply
SPDT Analog Switch
The NLAST4599 is an advanced high speed CMOS single pole -
double throw analog switch fabricated with silicon gate CMOS
technology. It achieves high speed propagation delays and low ON
resistances while maintaining low power dissipation. This switch
controls analog and digital voltages that may vary across the full
power-supply range (from V_CC to GND).
The device has been designed so the ON resistance (R_ON) is much
lower and more linear over input voltage than R_ON of typical CMOS
analog switches.
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.
