SOTinyTM Low Voltage Dual SPDT Analog Switch 2:1 Mux/DeMux Bus Switch
Description
Features
e DIODES PI5A3157 is a 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 operat-
ing power supply voltage range, 1.65V to 5.5V, the PI5A3157 has a
maximum ON resistance of 12Ω at 1.65V, 9Ω at 2.3V & 6Ω at 4.5V.
