STG3689 Low Voltage 0.9Ω max dual SPDT Switch with break-before-make feature 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) 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. The nIN inputs are provided to control the switches. TDFN10 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 immunity and transient excess voltage.
