Description
The PI3A3160C is a high-bandwidth, fast Dual 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 range, 1.5V to 4.2V ±10%, the switch has a typical
On-Resistance of 0.8Ω 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, inde-
pendent of supply voltage.
PI3A3160C is a lower voltage and On-Resistance replacement
for the PI5A3158.
