STG3684A - dual SPDT switch

General Description

The STG3684A is a high-speed CMOS dual analog SPDT (single-pole dual-throw) switch or dual 2:1 multiplexer/demultiplexer bus switch fabricated using silicon gate C2MOS technology.

Designed to operate from 1.65 to 4.3 V, this device is ideal for portable applications.

Key Features

  • Ultra low power dissipation: ICC = 0.2 μA (max. ) at TA = 85 °C Low ON resistance VIN = 0 V:.
  • RON = 0.45 Ω (max. TA = 25 °C) at VCC = 4.3 V.
  • RON = 0.50 Ω (max. TA = 25 °C) at VCC = 3.6 V.
  • RON = 0.50 Ω (max. TA = 25 °C) at VCC = 3.0 V Wide operating voltage range: VCC (OPR) = 1.65 to 4.3 V single supply 4.3 V tolerant and 1.8 V compatible threshold on digital control input at VCC = 2.3 to 4.3 V Latch-up performance exceeds 300 mA (JESD 17) ESD performance: H.
