STG3157

The STG3157 is an high-speed spdt CMOS ANALOG S.P.D.T. (Single Pole Dual Throw) SWITCH or 2:1 Multiplexer/Demultiplexer Bus switch fabricated in silicon gate C²MOS tecnology. It designed to operate from 1.65V to 5.5V, making this device ideal for portable applications.

STG3157 offers very low ON-Resistance (<9) at V_CC=3.0V. The IN input is provided to control the S.P.D.T. switch, it's compatible with standard CMOS output. The switch S1 is ON (it is connected to common Port D) when the IN input is held high and OFF (high impedance state exists between the two ports) when IN is held low; the switch S2 is ON (it is connected to common Port D) when the IN input is held low and OFF (high impedance state exists between the two ports) when IN is held high. Additional key faetures are fast switching speed, Break Before Make Delay Time and Very Low Power Consumption. All inputs and output are equipped with protection circuits against static discharge, giving them ESD immunity and transient excess voltage.

STG3157 is available in the commercial temperature range in smallest six lead smd package on the market.
