TMUX1121DGKR Description

Short technical summary and product information.

The TMUX1121DGKR from Texas Instruments is a precision complementary metal-oxide semiconductor (CMOS) device featuring two independently selectable 1:1, single-pole, single-throw (SPST) switches. This analog switch supports bidirectional analog and digital signals.

 

Key electrical characteristics include a wide operating supply voltage range from 1.08V to 5.5V. It offers a typical on-resistance of 1.9 Ohms and a bandwidth of 300MHz. The device exhibits low leakage current, with an on-state leakage of 3pA and a supply current of 0.007µA typical. Charge injection is minimized at -1.5pC, and crosstalk is -90dB at 10MHz.

 

Designed for a broad array of applications, the TMUX1121DGKR operates within an extended temperature range of -40°C to 125°C. It features 1.8V compatible control inputs and fail-safe logic. The switch supports rail-to-rail operation and bidirectional signal paths. ESD protection is rated at 2000V HBM.

 

Packaged in an 8-VSSOP, the TMUX1121DGKR is suitable for surface mount applications. The package is also described as 8-TSSOP, 8-MSOP (0.118", 3.00mm Width). Its robust design makes it applicable in systems requiring precise signal switching.
