Overview

The TMUX1208PWR is a high-performance, general-purpose 8:1 complementary metal-oxide semiconductor (CMOS) multiplexer. It features a broad supply range from 1.08V to 5.5V and supports bidirectional analog and digital signals from rail to rail. With a low leakage current of 10nA and extremely low power consumption, it is optimized for high-precision measurement applications and battery-powered systems.

Why Choose This Part

This multiplexer offers a 73MHz bandwidth and low 3-ohm typical on-resistance, ensuring signal integrity across a variety of frequencies. The fail-safe logic feature allows voltages on the control pins to exceed VDD, protecting the device from damage during power sequencing. Its 1.8V logic compatibility ensures seamless interfacing with modern low-voltage microcontrollers without external level shifters.

Applications

Sensor Signal Multiplexing
Switching multiple analog sensor inputs into a single ADC channel for environmental monitoring or industrial instrumentation.
Electronic Point of Sale (ePOS)
Managing peripheral signal routing and user interface inputs in compact, portable payment terminals.
Battery-Powered Handhelds
Extending battery life in mobile devices using its ultra-low 10nA standby current and 1.08V operation.
HVAC Control Systems
Polling multiple temperature or humidity sensors across various zones in climate control units.

Getting Started

Implementation requires decoupling the VDD pin with a 0.1uF capacitor placed close to the TSSOP-16 package. Design the PCB layout with short signal traces to maintain the 73MHz bandwidth and minimize parasitic capacitance. Ensure that the logic control pins are driven to a valid state, as they are 1.8V logic compatible across the entire supply range.
