SOTINYTM Low Voltage Dual SPDT Analog Switch

2:1 Mux/DeMux Bus Switch

Description

The PI5A3158 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

supplyvoltagerange,1.65Vto5.5V,thePI5A3158hasamaximum

On-Resistance of 12Ω at 1.65V, 9Ω at 2.3V & 6Ω at 4.5V.

Break-before-make switching prevents both switches being

enabled simultaneously. This eliminates signal disruption during

switching.

The control input, S, tolerates input drive signals up to 5.5V,

independent of supply voltage.
