switch

Datasheet

- production data

Features

 Ultra low power dissipation:

–ICC = 1 A (max.) at TA = 85 °C

 Low “ON” resistance:

–RON = 4.8  (TA = 25 °C) at VCC = 4.3 V

–RON = 5.9  (TA = 25 °C) at VCC = 3.0 V

 Wide operating voltage range:

–VCC (opr.) = 1.65 V to 4.3 V

 4.3 V tolerant and 1.8 V compatible threshold

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

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

channels

 USB (2.0) high speed (480 Mbps) signal

switching compliant

 Integrated fail safe function

 Interrupt function to indicate to the processor

that the device is in dedicated port charging

mode

 Latch-up performance exceeds 500 mA per

JESD 78, Class II

 ESD performance exceeds JESD22:

– Dn pins: 4000-V human body model (A114-

A)

– All other pins: 2000-V human body model

(A114-A)

Applications

 Wearable

 Sport and fitness

 Portable equipment

Description

The AS21P2THB is a high-speed CMOS low

voltage dual analog SPDT (single pole double

throw) switch or 2:1 multiplexer/demultiplexer

switch fabricated in silicon gate C²MOS

technology. It is designed to operate from 1.65 V

to 4.3 V, thus making this device the ideal

selection for portable applications.

The SEL input is provided to control the switch.

The switch nS1 is ON (connected to common

ports Dn) when the SEL input is held high and

OFF (high impedance state exists between the

two ports) when SEL is held low, the switch nS2 is

ON (it is connected to common port Dn) when the

SEL input is held low and OFF (high impedance

state exists between the two ports) when SEL is

held high. AS21P2THB has an integrated fail safe

function to withstand over-voltage condition when

the device is powered off.

The AS21P2THB also has an interrupt pin which

sends a signal to the processor when the device

is in dedicated port charging mode. 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.
