Description
General part information
TMUX7234 Series
The TMUX7234 is a complementary metal-oxide semiconductor (CMOS) multiplexer with latch-up immunity. The TMUX7234 contains four independently controlled SPDT switches with an EN pin to enable or disable all four channels. The device supports 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 TMUX7234 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 1.8 V 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 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.
