Description
The STG3155 is a high-speed CMOS low voltage single 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
■ High speed:
   – tPD = 1.5ns (Typ.) at VCC = 3.0V
   – tPD = 1.5ns (Typ.) at VCC = 2.3V
■ Ultra low power dissipation:
   – ICC = 0.2µA (Max.) at TA = 85°C
■ Low "ON" resistance:
   – RON = 0.5Ω (TA = 25ºC) at VCC = 4.3V
   – RON = 0.6Ω (TA = 25ºC) at VCC = 3.0V
   – RON = 1.0Ω (TA = 25ºC) at VCC = 1.8V
■ 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 = 2.3V to 3.0V
■ Latch-up performance exceeds 300mA (JESD 17)
■ ESD Performance (Analog Chan. Vs. GND): HMB >2kV (MIL STD 883 method 3015)
