TMUX1574PWR SPDT analog multiplexer
The TMUX1574PWR from Texas Instruments is a high-performance, low-power 4-channel single-pole double-throw (SPDT) analog multiplexer designed for precision signal routing in space-constrained applications. This advanced CMOS switch operates from a single 1.8V to 5.5V supply voltage and features an ultra-low on-resistance of just 0.5Ω typical with exceptional flatness across the signal path, making it ideal for data acquisition systems, test equipment, and portable medical devices where signal integrity is critical. Housed in a compact 16-pin TSSOP package, the device supports bidirectional signal flow with a wide -5V to +5V analog signal range and offers a high bandwidth of 900 MHz, enabling seamless switching of high-speed signals while consuming minimal power. The TMUX1574PWR incorporates break-before-make switching action to prevent signal shorting during transitions and features 1.8V logic-compatible digital inputs, providing a robust solution for multiplexing analog signals in battery-powered electronics, sensor interfaces, and communication systems.
TMUX1574PWR Applications
The TMUX1574PWR is extensively used in portable medical equipment for ECG signal routing, patient monitoring systems, and diagnostic instruments where its low on-resistance and high accuracy ensure precise biomedical signal acquisition. Industrial automation systems employ the device for sensor multiplexing in PLCs, data acquisition cards, and process control equipment requiring reliable signal switching in noisy environments. Test and measurement applications include oscilloscopes, spectrum analyzers, and automated test equipment where the multiplexer's high bandwidth and low distortion maintain signal integrity during channel selection. Audio/video systems utilize the IC for input selection in mixers, switchers, and professional audio equipment benefiting from its low THD characteristics.
