3 Description

•

Latch-Up Immune

The TMUX7208 is a precision 8:1, single channel

multiplexer while the TMUX7209 is a 4:1, 2 channel

multiplexer featuring low on resistance and charge

injection. 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 TMUX720x support bidirectional analog and

digital signals onthe source (Sx) and drain (D) pins

Dual Supply Range: ±4.5 V to ±22 V

Single Supply Range: 4.5 V to 44 V

Low On-Resistance: 4 Ω

Low Charge Injection: 3 pC

High Current Support: 400 mA (Maximum)

Rail-to-Rail Operation

Bidirectional Signal Path

The TMUX720x 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.

The TMUX72xx 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 TMUX72xx family of switches and

multiplexers to be used in harsh environments.
