Description

The STG5123 is a high-speed CMOS low voltage

single analog SPDT (single-pole dual-throw)

switch or 2:1 multiplexer/demultiplexer switch

fabricated using silicon gate C2MOS technology.

Designed to operate from 1.65 to 4.5 V, this

device is ideal for portable applications.

The device offers very low ON resistance (1

Ω) at

VCC = 4.5 V. The switch S1 is ON (connected to

common ports Dn) when the SEL input is held

high and OFF (state of 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 SEL input is held low and OFF

(state of high impedance state exists between the

two ports) when SEL 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 and transient excess voltage

immunity.
