TMUX6104 4:1 Precision Analog Multiplexer Texas Instruments TMUX6104 4:1 Precision Analog Multiplexer is a modern complementary metal-oxide semiconductor (CMOS) analog multiplexer (MUX) that offers 4:1 single-ended multiplexing. The devices work well with dual supplies (±5V to ±16.5V), a single supply (10V to 16.5V), or unsymmetric supplies (such as VDD = 12V, VSS = –5V). All digital inputs have transistor-transistor logic (TTL) compatible thresholds, ensuring compatibility with both TTL and CMOS logic.
