AS21P2TLR

Low voltage 0.5 Ω max dual single-pole double-throw analog switch

with break-before-make

Datasheet

Features

 Wide operating voltage range:

 4.3 V tolerant and 1.8 V compatible threshold

 Latch-up performance exceeds 300 mA

(JESD 17)

 ESD performance: HMB > 2 kV (MIL STD 883

method 3015)

Description

The AS21P2TLR is a high-speed CMOS single-

pole double-throw (SPDT) analog 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.

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 ultralow power consumption. All inputs

and outputs are equipped with protection circuits

against static discharge, giving them ESD and

excess transient voltage immunity.
