•
•
•
Pericom Semiconductor's PI3A212 is a dual high-bandwidth, fast
single-pole double throw (SPDT) CMOS switch. It can be used as
an analog switch or as a low-delay bus switch. Specified over a
wide operating power supply voltage, 2.7V to 4.2V, the PI3A212
has an On-Resistance of 0.6Ω at +2.7V.
CMOS Technology for Bus and Analog Applications
Low On-Resistance: 0.6Ω.
Wide VCC Range: 2.7V to 4.2V ±10%
Rail-to-Rail Signal Range
High Off Isolation: -75dB @ 100kHz
Crosstalk Rejection Reduces Signal Distortion:
-90dB @ 100kHz
• Break-Before-Make Switching
• Extended Industrial Temperature Range: –40°C to 85°C
• Packaging (Pb-free & Green): 10-contact TQFN (ZL10)
Break-before-make switching prevents both switches being enabled simultaneously. This eliminates signal disruption during
switching.

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 inut and output diode current ratings are observed.
3. Control input must be held HIGH or LOW; it must not float.
