PI3A412E
0.5Ω, 3.3V, Quad SPDT Analog Switch with Enable
Features
Description
• CMOS Technology for Bus and Analog Applications
The PI3A412E is a Quad single-pole double-throw (SPDT) CMOS
switch with enable. It can be used as an analog switch or as a lowdelay bus switch. Specified over a wide operating power supply
voltage range, +1.65V to +4.2V, the switch has an On-Resistance
of 0.5Ω at 2.7V.
• Low On-Resistance: 0.5Ω (+2.7V Supply)
• Wide VCC Range: +1.65V to +4.2V ±10%
• ICC = 0.3μA @ TA = +25˚C
• Rail-to-Rail switching throughout Signal Range
Control inputs, A0 to EN, tolerates input drive signals up to 5V,
independent of supply voltage.
• Fast Switching Speed: 20ns max. at 3.3V
• High Off Isolation: -65dB @ 100 kHz
• Crosstalk Rejection: -65dB @ 100 kHz
• Extended Industrial Temperature Range: –40°C to 85°C

Caution: Stresses beyond those listed under “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.

Notes:
1. The algebraic convention, where most negative value is a minimum and most positive is a maximum, is used in this data sheet.
2. Typical values are TA = 25°C, VCC = 4.2V unless otherwise specified.
3. Guaranteed by design.
4. ΔRON = RON match between channels
5. Flatness is defined as the difference between the maximum and minimum value of On-Resistance measured.
