Description
The 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.

Features
■ Low quiescent supply current:
   – Max ±50µA for V1IN, V2IN = 1.80V at VCC = 4.3V
■ Ultra low power dissipation:
   – ICC = 0.2µA (Max.) at TA = 85°C, VIN = 0V
■ Switch S1: Low “ON” resistance VIN = 0V:
   – RON = 0.7Ω (Max. TA =25°C) at VCC = 4.3V
   – RON = 0.9Ω (Max. TA = 25°C) at VCC = 3V
■ Wide operating voltage range:
   – VCC (OPR) = 1.65V to 4.3V single supply
■ 4.3V Tolerant and 1.8V compatible threshold on digital control input at VCC = 1.65 to 4.3V
■ Latch-up performance exceed 300mA (JESD 17)
■ ESD performance (Analog chan. Vs. GND):
   HBM >2kV (MIL STD 883 method 3015)
