TMUX7236

The TMUX7236 is a complementary metal-oxide semiconductor (CMOS) switch with latch-up immunity in a dual channel, 2:1 configuration. The device works well with dual supplies (±5 V to ±22 V), a single supply (5 V to 44 V), or asymmetric supplies (such as V DD = 12 V, V SS = –5 V). The TMUX7236 supports bidirectional analog and digital signals on the source (Sx) and drain (D) pins ranging from V SS to V DD.

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.

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.
