The TMUX722x are complementary metal-oxide semiconductor (CMOS) switches with latch-up immunity in a dual channel, 1:1 (SPST) configuration. These 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 TMUX722x supports bidirectional analog and digital signals on the source (Sx) and drain (D) pins ranging from V SS to V DD.

The TMUX722x can be enabled or disabled by controlling the SEL pins, turning on signal path 1 (S1 to D1) or signal path 2 (S2 to D2). All logic control inputs support logic levels from 1.8 V to V DD, allowing for both TTL and CMOS logic compatibility when operating in the valid supply voltage range. Fail-safe logic circuitry allows voltages on the control pins to be applied before the supply pin, protecting the device from potential damage. For more information, see .

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.
