The TMUX622x are complementary metal-oxide semiconductor (CMOS) switch in a dual channel, 1:1 (SPST) configuration. The device works with a single supply (4.5 V to 36 V), dual supplies (±4.5 V to ±18 V), or asymmetric supplies (such as VDD = 12 V, VSS = –5 V). The TMUX622x supports bidirectional analog and digital signals on the source (Sx) and drain (D) pins ranging from VSS to VDD.
The TMUX622x can be enabled or disabled by controlling the SEL pins, turning on signal path 1 (S1 to D1) or signal path 2 (S2 to D2). All logic control inputs support logic levels from 1.8 V to VDD, 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 TMUX622x is part of the precision switches and multiplexers family of devices. These devices have very low on and off leakage currents, 50 pA, allowing them to be used in high precision measurement applications.

The TMUX-10DGS-EVM is used to evaluate the performance of the 10-pin DGS package. The evaluation module (EVM) comes with a pad to allow 10-pin DGS devices to be soldered. Additionally, test points on board are provided to allow for the flexibility to test for various signals.
The EVM-LEADED1 board allows for quick testing and bread boarding of TI's common leaded packages. The board has footprints to convert TI's D, DBQ, DCT,DCU, DDF, DGS, DGV, and PW surface mount packages to 100mil DIP headers.
