The TMUX7208EVM supports evaluation of the TMUX7208 device in the 16-pin TSSOP (PW) package. TMUX7208 is a complementary metal-oxide semiconductor (CMOS) switch with latch-up immunity in a 8:1 single channel configuration. The device supports dual supplies (±4.5 V to ±22 V), a single supply (4.5 V to 44 V), or asymmetric supplies (such as VDD = 12 V, VSS = –5 V). The TMUX7208 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. The Fail-Safe Logic circuitry applies voltages on the control pins before the supply pin, which protects the device from potential damage.
