PI3A223C
Dual SPDT Analog Switch with Negative
Signal Support for AC Coupled Signals
Features
Description
• CMOS Technology for Bus and Analog Applications
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.
• Low On-Resistance: 0.6Ω.
• V Range: 2.7V to 4.2V
DD
• V
tolerance down to -1.5V
INPUT
Break-before-make switching prevents both switches being
enabled simultaneously. This eliminates signal disruption during
switching.
• High Off Isolation: -80dB @ 100kHz
• Integrated ESD protection up to 2kV HBM
• Crosstalk Rejection Reduces Signal Distortion:
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.
-80dB @ 100kHz
• Input signals can be from -1.5V up to +3.6V without
distortion.
• Break-Before-Make Switching
• Extended Industrial Temperature Range: –40°C to 85°C
• Packaging (Pb-free & Green):
− 10-contact TQFN (ZM10) 1.4×1.8

Notes:
1. "Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any
other conditions beyond those indicated in the operational sections of this specification is not implied.
2. The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed.
3. Control input must be held HIGH or LOW; it must not float.
