TMUX1308QBQBRQ1 CMOS analog multiplexer 8:1 single-channel
The TMUX1308QBQBRQ1, manufactured by Texas Instruments, is an AEC-Q100 qualified high-performance CMOS 8:1 single-channel analog multiplexer designed for automotive and industrial applications. Housed in a compact 16-pin WQFN package with tape-and-reel packaging for automated assembly, it operates reliably across a wide temperature range of -40°C to 125°C (Grade 1), ensuring stable performance in harsh environments. This device features bidirectional signal paths supporting both analog and digital signals from GND to VDD, with three binary control inputs (A, B, C) and an enable input for precise channel selection, making it a versatile solution for signal routing and switching in various electronic systems.
This multiplexer offers exceptional electrical characteristics tailored for modern low-voltage applications, including a wide single-supply voltage range of 1.62V to 5.5V, supporting 1.8V, 2.5V, 3.3V, and 5V power rails. It exhibits low on-resistance (typical 59Ω at VDD=5V), low channel capacitance (typical 11pF), and ultra-low supply current (typical 0.003µA), ensuring minimal signal distortion and power consumption. The device integrates injection current control, back-powering protection, and short-to-battery protection, eliminating the need for external protection components and enhancing system reliability. It also features break-before-make switching, fail-safe logic, rail-to-rail operation, and 1.8V logic compatibility, with a high bandwidth of 500MHz for high-frequency signal processing.
