Description

The STG5123 is a high speed CMOS low voltage
single analog SPDT (single-pole double-throw)
switch or 2:1 multiplexer/demultiplexer switch
manufactured using silicon gate C
technology. Designed to operate from a 1.65 to

4.5 V supply, this device is ideal for portable
applications.

The device offers very low ON-resistance (1 Ω)
at V

= 4.5 V. Switch S1 is ON (connected to

CC

common ports Dn) when the SEL input is held
high, and OFF (state of high impedance exists
between the two ports) when SEL is held low.

Switch S2 is ON (connected to common port D)
when the SEL input is held low, and OFF (state
of high impedance 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 to protect against static
discharge, giving them immunity from ESD and
transient excess voltage.
