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 C
2
MOS 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
惟)
at
V
CC
= 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.
