STG3384 Low voltage 0.9Ω max dual SPST 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: low "ON" resistance: – RON = 0.7Ω (Max TA = 25°C) at VCC = 4.3V – RON = 0.7Ω (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 exceeds 300mA (JESD 17) ■ ESD performance (analog channel vs GND): HBM > 2kV (MIL STD 883 method 3015) TDFN10 Description The STG3384 is a high-speed CMOS low voltage dual analog S.P.S.T. (Single Pole Single Throw) SWITCH fabricated in silicon gate C2MOS technology. It is designed to operate from 1.65V to 4.3V, making this device ideal for portable. The nIN inputs are provided to control the switches. The switches Sn 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. 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.
