PI3A223C
Dual SPDT Analog Switch with Negative
Signal Support for AC Coupled Signals
Description
Pericom Semiconductor's PI3A223C is a dual, fast single-pole
double throw (SPDT) CMOS switch. It can be used as an ana-
log switch or as a low-delay bus switch. The PI3A223C has an
On-Resistance of 0.6Ω at +2.8V.
Break-before-make switching prevents both switches being
enabled simultaneously. This eliminates signal disruption during
switching.
With the use of 3rd party headsets, AC coupling is required to
protect against EOS damage caused by DC offsets. Pericom’s
PI3A223C can support these AC coupled audio signals, since
the switch can tolerate signals down to -1.5V without a negative
power supply.
