Description
The STG5223 is a high-speed CMOS dual analog
SPDT (single pole dual throw) switch or dual 2:1
multiplexer/demultiplexer bus switch fabricated in
silicon gate C
2
MOS technology. It is designed to
operate from 1.65 to 4.3 V, making this device
ideal for portable applications.
It offers very low ON resistance (<0.5

= 3.0 V. The nIN inputs are provided to
control the switches. The switches nS1 are ON
(connected to common ports Dn) when the nIN
input is held high and OFF (high impedance state
exists between the two ports) when nIN is held
low. The switches nS2 are ON (connected to
common ports Dn) when the nIN input is held low
and OFF (high impedance state exists between
the two ports) when IN 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 immunity.
