Description
The STG3856 is a high-speed CMOS LOW
VOLTAGE DUAL ANALOG S.P.3.T. (Single Pole
Triple Throw) SWITCH or Dual 3:1 Multiplexer /
Demultiplexer Switch fabricated in silicon gate
C²MOS technology. It is designed to operate from
1.65V to 4.3V, making this device ideal for
portable applications.
The device offers very low ON-Resistance
(<1.0Ω) at V_CC = 4.3V. The disabling and enabling
of switches are done by setting the 1IN and 2IN
control pins. Additional key features are fast
switching speed, 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.
