STG3157 - Low voltage low on-resistance SPDT switch

General Description

The STG3157 is a high-speed CMOS analog SPDT (single-pole double-throw) switch or 2:1 multiplexer/demultiplexer bus switch manufactured using silicon gate CMOS technology.

It is designed to operate from a 1.65 V to 5.5 V supply, making the device ideal for portable applications.

Key Features

  • High speed:.
  • tPD = 0.3 ns (max) at VCC = 4.5 V.
  • tPD = 0.8 ns (max) at VCC = 3.0 V.
  • tPD = 1.2 ns (max) at VCC = 2.3 V.
  • Ultra low power dissipation:.
  • ICC = 1 μA (max) at TA = 85 °C.
  • Low on-resistance; at VIN = 0 V:.
  • RON = 7 Ω (max TA = 85 °C) at VCC = 4.5 V.
  • RON = 9 Ω (max TA = 85 °C) at VCC = 3.0 V.
  • Wide operating voltage range:.
  • VCC (OPR) = 1.65 V to 5.5 V single supply.
  • TTL threshold ON.
