Descriptions
DIO23157 is a dual, bidirectional,
single-pole/double-throw (SPDT) CMOS analog
switch, which is designed to operate from a
single 1.8V to 5.5V supply. It features
high-bandwidth (300MHz) and low on-resistance,
targeted applications for full speed USB and
audio switching.
DIO23157 features power ON/OFF protection
effectively protecting device against external
signal perturbation. It also offers excellent -3db
bandwidth and lower ON resistance, which can
be used as analog switch in multiple
applications.
It operates under wide VCC supply from 1.8V to
5.5V, consuming very low quiescent current even
when the voltage of IN 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.
