Texas Instruments TMUX7236 2:1 (SPDT) 2-Channel Precision Switch 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 (±5V to ±22V), a single supply (5V to 44V), or asymmetric supplies (such as VDD = 12V, VSS = –5V). The TMUX7236 supports bidirectional analog and digital signals on the source (Sx) and drain (D) pins ranging from VSS to VDD.
All logic control inputs support logic levels from 1.8V to VDD, ensuring 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 Texas Instruments TMUX72xx family provides latch-up immunity. This feature prevents undesirable high current events between parasitic structures within the device, typically caused by overvoltage events. A latch-up condition usually 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.
