Overview
The TMUX1219DCKR is a general-purpose complementary metal-oxide semiconductor (CMOS) single-pole double-throw (SPDT) switch produced by Texas Instruments. This device is designed to switch between two source inputs based on the state of the SEL pin. It operates over a wide supply range of 1.08 V to 5.5 V, making it versatile for various applications from personal electronics to building automation. The TMUX1219 supports bidirectional analog and digital signals on the source (Sx) and drain (D) pins, ranging from GND to VDD. Its low supply current of 4 nA and fail-safe logic features make it suitable for portable and complex system designs.
