Introducing the TMUX1108PWR from Texas Instruments

The TMUX1108PWR is a precision, low-on-resistance, 8:1, single-channel multiplexer from Texas Instruments (TI), designed for exceptional performance in a wide range of applications. This advanced switch is ideal for signal routing in various systems, including data acquisition, communication equipment, and industrial process control, where a high degree of reliability and efficiency is required.

At the heart of the TMUX1108PWR's design is its low charge injection, low power consumption, and ESD protection of ±4 kV (HBM), which ensures minimal impact on signal integrity and robustness in harsh environments. The device operates from a single supply range of 1.08 V to 5.5 V, making it versatile for both portable and fixed power applications. Its wide operating temperature range from -40°C to +125°C guarantees reliable performance under extreme conditions.

With a bidirectional signal flow, the TMUX1108PWR can pass signals from the common port (D) to one of the eight normally open (NO) ports or vice versa, without the need for additional signal inversion. Its low-on-resistance of typically 2.5 ohms ensures minimal signal distortion and voltage drop, making it an excellent choice for precision applications.

The TMUX1108PWR also features break-before-make switching, which prevents signal overlap during channel transitions and protects against shorting and signal degradation. Its compact TSSOP-16 package allows for a minimal footprint on PCBs, providing a space-efficient solution for high-density designs.

For design flexibility, the TMUX1108PWR includes an array of logic-compatible control inputs, which simplify interfacing with a variety of microprocessors and digital systems. The device's fail-safe logic ensures that all channels are turned off in the event of a power loss, further enhancing system safety.

TI's commitment to quality and performance is evident in the TMUX1108PWR, making it a reliable and efficient choice for designers seeking a high-performance multiplexer for their next project. With its combination of low-on-resistance, precision signal handling, and robust construction, the TMUX1108PWR is poised to meet the demanding requirements of today's sophisticated electronic systems.
