PI3A3160C
3.0V, SOTinyTM 0.8 Dual SPDT Analog Switch with -1.0V to 4.2V Operating Range
Features
* Analog Signal Range: -1.0V to VCC when switch is "ON" * -1.0V Undershoot Protection when switch is "OFF" * CMOS Technology for Bus and Analog Applications * Low On-Resistance: 0.8 (+3.3V Supply) * Wide VCC Range: 1.5V to 4.2V 10% * Low Power Consumption : 5W * Rail-to-Rail switching throughout Signal Range * Fast Switching Speed: 50ns max. at 3.3V * High Off Isolation: -50dB at 1 MHz * -45dB (1 MHz) Crosstalk Rejection Reduces Signal Distortion * Break-Before-Make Switching * Extended Industrial Temperature Range: -40C to 85C * Packaging: (Pb-free & Green) -12-contact TDFN (ZE) -12-contact TDFN (ZG)
Description
The PI3A3160C is a high-bandwidth, fast Dual single-pole doublethrow (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 range, 1.5V to 4.2V 10%, the switch has a typical On-Resistance of 0.8 at 3.3V. Break-before-make switching prevents both switches from being enabled simultaneously. This eliminates signal disruption during switching. Control inputs, IN, tolerates input drive signals up to 3.3V, independent of supply voltage. PI3A3160C is a lower voltage and On-Resistance replacement for the PI5A3158.
