The STG3692 is a high-speed CMOS low voltage quad analog SPDT (single pole
dual throw) switch or 2:1 multiplexer /demultiplexer switch developed in silicon gate
C2MOS technology. It is designed to operate from 1.65 V to 4.3 V, making this device
ideal for portable applications.
The nSEL inputs are provided to control the switch. The switch S1 is ON (connected
to common ports Dn) when the nSEL input is held high and OFF (high impedance
state exists between the two ports) when SEL is held low; the switch S2 is ON
(connected to common port D) when the nSEL input is held low and OFF (high
impedance state exists between the two ports) when nSEL is held high. Additional
key features are fast switching speed, break-before-make delay time and ultra low
power consumption. All inputs and outputs are equipped with protection circuits
against static discharge, giving them ESD immunity and transient excess voltage.
