TMUX721x 44 V, Low-RON, 1:1 (SPST), 4-Channel Precision Switches with Latch-Up

Immunity and 1.8-V Logic

1 Features

3 Description

•

Latch-Up Immune

The TMUX7211, TMUX7212, and TMUX7213 are

complementary metal-oxide semiconductor (CMOS)

switches with four independently selectable 1:1,

single-pole, single-throw (SPST) switch channels. The

devices work with a single supply (4.5 V to 44 V), dual

supplies (±4.5 V to ±22 V), or asymmetric supplies

(such as V_DD= 12 V, V_SS= –5 V). The TMUX721x

supports bidirectional analog and digital signals on the

source (Sx) and drain (Dx) pins ranging from V_SSto

Dual Supply Range: ±4.5 V to ±22 V

Single Supply Range: 4.5 V to 44 V

Low On-Resistance: 2 Ω

High Current Support: 330 mA (Maximum)

(WQFN)

High Current Support: 220 mA (Maximum)

(TSSOP)

–40°C to +125°C Operating Temperature

Rail-to-Rail Operation

Bidirectional Operation

The switches of the TMUX721x are controlled with

appropriate logic control inputs on the SELx pins. The

TMUX721x are part of the precision switches and

multiplexers family of devices and have very low on

and off leakage currents allowing them to be used in

high precision measurement applications.

2 Applications

•

Sample-and-Hold Circuits

Feedback Gain Switching

Signal Isolation

The TMUX721x family provides latch-up immunity,

preventing undesirable high current events between

parasitic structures within the device typically caused

by overvoltage events. A latch-up condition typically

continues until the power supply rails are turned off

and can lead to device failure. The latch-up immunity

feature allows the TMUX721x family of switches and

multiplexers to be used in harsh environments.
