DESCRIPTION
The STG3157 is an high-speed spdt CMOS ANALOG S.P.D.T. (Single Pole Dual Throw) SWITCH or 2:1 Multiplexer/Demultiplexer Bus Switch fabricated in silicon gate C2MOS tecnology. It designed to operate from 1.65V to 5.5V, making this device ideal for portable applications.

■ HIGH SPEED:
   tPD = 0.3ns (MAX.) at VCC = 4.5V
   tPD = 0.8ns (MAX.) at VCC = 3.0V
   tPD = 1.2ns (MAX.) at VCC = 2.3V
■ VERY LOW POWER DISSIPATION:
   ICC = 1µA(MAX.) at TA=85°C
■ LOW "ON" RESISTANCE VIN=0V:
   RON=7Ω(MAX.TA=85°C) atVCC=4.5V
   RON = 9Ω (MAX. TA=85°C) at VCC = 3.0V
■ WIDE OPERATING VOLTAGE RANGE:
   VCC (OPR) = 1.65V to 5.5V SINGLE SUPPLY
■ TTL THRESOLD ON CONTROL INPUT at VCC = 2.7 to 3.6V
■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 3157
■ LATCH-UP PERFORMANCE EXCEEDS 300mA (JESD 17)
