Features

■ Low quiescent supply current:

–Max

±50µA for V

1IN, V2IN = 1.80V

at VCC = 4.3V

■ Ultra low power dissipation:

–ICC = 0.2µA (Max.) at TA = 85°C, VIN = 0V

■ Switch S1: Low “ON” resistance VIN = 0V:

–RON = 0.7Ω (Max. TA =25°C) at VCC = 4.3V

–RON = 0.9Ω (Max. TA = 25°C) at VCC = 3V

■ 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 = 1.65 to 4.3V

■ Latch-up performance exceed 300mA (JESD

17)

■ ESD performance (Analog chan. Vs. GND):

HBM >2kV (MIL STD 883 method 3015)

Description

The STG3689 is a high-speed CMOS low voltage

dual 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.

The nIN inputs are provided to control the

switches.

The switches nS1 are ON (they are

connected to common Ports Dn) when the

nIN input is held high and OFF (high

impedance state exists between the two

ports) when nIN is held low. The switches

nS2 are ON (they are connected to common

Ports Dn) when the nIN input is held low and

OFF (high impedance state exists between

the two ports) when IN is held high.

Additional key features are fast switching speed,

and ultra low power consumption. All inputs and

outputs are equipped with protection circuits

against static discharge, giving them ESD

immunity and transient excess voltage.
