Descriptions
The DIO3157E is an enhanced single-pole
double-throw (SPDT) CMOS analog switch. It
features power ON/OFF protection on common
ports effectively protecting device against
external signal perturbation. It also offers
excellent -3 dB bandwidth and lower ON
resistance, which can be used as analog
switch in multiple applications.
The DIO3157E operates under wide VCC supply
from 1.65 V to 5.5 V, consuming very low
quiescent current even when the voltage of S
pin is lower than VCC supply. This new feature
services the mobile handset applications very
well allowing for the direct interface with
baseband processor general purpose I/Os with
no need of level translator.
