Low voltage high bandwidth quad DPDT switch

Datasheet - production data

Description

The STG3820 device is a high-speed CMOS low

voltage quad analog DPDT (dual pole dual throw)

switch or 2:1 multiplexer/demultiplexer switch

fabricated in silicon gate C MOS technology. It is

designed to operate from 1.65 V to 4.3 V, making

this device ideal for portable applications.

Flip Chip 30

(2.0 x 2.4 mm)

The SELm-n input is provided to control the

switches. The switches nS1 and mS1 are ON

(connected to common ports Dn and Dm

respectively) when the SELm-n input is held high

and OFF (high impedance state exists between

the two ports) when the SELm-n is held low. The

switches nS2 and mS2 are ON (connected to

common port Dn and Dm respectively) when the

SELm-n input is held low and OFF (high

Features

 Ultralow power dissipation

– I = 1 µA (max.) at T = 85 °C

impedance state exists between the two ports)

when the SELm-n is held high.

 Low “ON” resistance

– R = 5.4  (T = 25 °C) at V = 4.3 V

The STG3820 device has an integrated fail safe

function to withstand overvoltage condition when

the device is powered off. Additional key features

are fast switching speed, break-before-make-

delay time and ultralow power consumption. All

inputs and outputs are equipped with protection

circuits against static discharge, giving them ESD

immunity and transient excess voltage.

– R = 6.6  (T = 25 °C) at V = 3.0 V

 Wide operating voltage range

– V (OPR.) = 1.65 V to 4.3 V

 4.3 V tolerant and 1.8 V compatible threshold

on digital control input at V = 2.3 V to 3.0 V

 4 select pins controlling 2 switches each

 Typical bandwidth (-3 dB) at 800 MHz on all

channels
