STG3157 General Description

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.

It 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.

It's available in the commercial temperature range in smallest six lead smd package on the market.

STG3684 General Description

The STG3684 is an high-speed CMOS DUAL NALOG S.P.D.T. (Single Pole Dual Throw) WITCH or DUAL 2:1 Multiplexer/Demultiplexer Bus Switch fabricated in silicon gate C2MO chnology. It is designed to operate from 1.65V to .3V, making this device ideal for portable pplications.

It offers very low ON-Resistance (<0.5) at CC=3.0V. The nIN inputs are provided to control he switches. The switches nS1 are ON (they are onnected to common Ports Dn) when the nIN nput is held high and OFF (high impedance state xists between the two ports) when nIN is held ow; the switches nS2 are ON (they are connected o common Ports Dn) when the nIN input is held ow and OFF (high impedance state exists etween the two ports) when IN is held high. dditional key features are fast switching speed, reak Before Make Delay Time and Ultra Low ower Consumption. All inputs and outputs are quipped with protection circuits against static charge, giving them ESD immunity and ransient excess voltage. It's available in the ommercial temperature range in the QFN ackage.
