DescriptionThe STG3689 is a high-speed CMOS low voltage dual analog S.P.D.T. (Single Pole Dual Throw) switch or 2:1 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.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, and ultra low power consumption. All inputs and outputs are equipped with protection circuits against static discharge, giving them ESD TDFN10 STG3689Low Voltage 0.9 max dual SPDT Switchwith break-before-make featurewww.st.comOrder codesPart numberPackagePackagingSTG3689DTRTDFN10 (2.5mm x 1.3mm Features Low quiescent supply current:Max 50A for V1IN, V2IN = 1.80V at VCC = 4.3VUltra low power dissipation:I CC = 0.2A (Max.) at TA = 85C, VIN = 0VSwitch S1: Low ON resistance VIN = 0V:R ON = 0.7 (Max.
