3 Description

The SN4599-Q1 is a general purpose complementary

metal-oxide semiconductor (CMOS) single-pole

double-throw (SPDT) switch. The SN4599-Q1

switches between two source inputs based on the

state of the SEL pin. Wide operating supply of 2V

to 5.5V allows for use in a broad array of automotive

applications. The device supports bidirectional analog

and digital signals on the source (Sx) and drain (D)

pins ranging from GND to VDD.
