Description

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.

It offers very low ON resistance (RON < 0.5 Ω) at VCC = 3.6 V. The nIN inputs are provided to

control the independent channel switches nS1 and nS2. The switches nS1 are ON

(connected to common ports Dn) when the nIN input is held high and OFF (state of high

impedance exists between the two ports) when nIN is held low. The switches nS2 are ON

(connected to common ports Dn) when the nIN input is held low and OFF (state of high

impedance exists between the two ports) when IN is held high. Additional key features are

fast switching speed, break-before-make delay time and ultra low power consumption. All

inputs and outputs are equipped with protection circuits against static discharge, giving

them ESD and excess transient voltage immunity.
