DESCRIPTION
The STG3690 is an high-speed CMOS LOW VOLTAGE QUAD ANALOG S.P.D.T. (Single Pole Dual Throw) SWITCH or 2:1 Multiplexer/ Demultiplexer Switch fabricated in silicon gate C 2MOS technology. It is designed to operate from 1.65V to 3.6V, making this device ideal for portable applications. It offers very low ON-Resistance (<5 Ω) at VCC=3.0V. The nIN inputs are provided to control the switches. The switches nS1 are ON (they are connected to common Ports Dn) when the nIN input is held high and OFF (high impedance state exists between the two ports) when nIN is held low; the switches nS2 are ON (they are connected to common Ports Dn) when the nIN 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 in TSSOP and QFN3x3mm package.
