The TMUX720x is a complementary metal-oxide semiconductor (CMOS) switch with latch-up immunity in a single channel, 1:1 (SPST) configuration. The device works with a single supply (4.5V to 44V), dual supplies (±4.5V to ±22V), or asymmetric supplies (such as VDD = 12V, VSS = –5V). The TMUX720x supports bidirectional analog and digital signals on the source (S) and drain (D) pin ranging from VSS to VDD.
The TMUX720x can be enabled or disabled by controlling the SEL pin. When disabled, both signal path switches are off. All logic control inputs support logic levels from 1.8V to VDD, which is compatible for both TTL and CMOS logic 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.
