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 (<1.0) at VCC = 4.3V. The disabling and enabling of switches are done by setting the 1IN and 2IN control pins. Additional key features are fast sw itching 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.

Maximum Ratings
Stressing the device above the rating listed in the "Absolute Maximum Ratings" table may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions above those indicated in the Operating sections of this specification is not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability. Refer also to the STMicroelectronics SURE Program and other relevant quality documents.
