DESCRIPTION The STG3685 is an high-speed CMOS DUAL ANALOG S.P.D.T. (Single Pole Dual Throw) SWITCH or DUAL 2:1 Multiplexer/Demultiplexer Bus Switch fabricated in silicon gate C2MOS technology. It is designed to operate from 1.4V to 4.3V, making this device ideal for portable applications. It offers very low ON-Resistance (<0.5) at VCC=3.0V. The IN input is provided to control the switches. The switches nS1 are ON (they are

connected to common Ports Dn) when the IN input is held high and OFF (high impedance state exists between the two ports) when IN is held low; the switches nS2 are ON (they are connected to common Ports Dn) when the IN 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. It's available in the commercial temperature range Flip-chip package with Epoxy Protection.
