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 VDD = 12 V, VSS = –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)
(WQFN)

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.
