Overview
The TMUX1111RSVR is a precision analog switch IC from Texas Instruments, featuring four independent single-pole single-throw (SPST) channels in a UQFN-16 package. It operates on a single supply voltage ranging from 1.08 V to 5.5 V with a maximum quiescent current of 1 uA. The device supports bidirectional analog and digital signals between ground and the supply rail, offering a maximum on-state resistance of 4.9 Ohms and an on-state leakage current of 3 pA. It functions within a temperature range of -40°C to +125°C and handles a maximum switch DC current of 30 mA.
Feature Summary
- Ultra-low power consumption with 1 uA maximum supply current
- High precision performance characterized by 3 pA on-state leakage current
- Supports bidirectional signal transmission across the full supply range
Applications
- Medical equipment requiring low leakage and high precision
- Industrial systems operating under wide temperature conditions
- Portable instrumentation powered by single supply rails
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout compatibility and package dimensions. Ensure that the UQFN-16 footprint matches the design layout requirements. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement specifications.
Selection Notes
Select this component when ultra-low leakage and minimal power consumption are critical for the application. The 1.08 V minimum supply voltage allows operation in battery-powered devices where energy efficiency is paramount. Verify that the 4.9 Ohm on-resistance meets the signal integrity requirements for the specific load being switched.
Part Context
This part belongs to the TMUX111x family of precision CMOS switches designed for applications demanding high accuracy and low power. The RSVR suffix indicates a specific reel-based packaging format suitable for automated surface-mount assembly processes. It shares core electrical characteristics with other variants in the series while differing primarily in physical packaging and shipping configuration.
Replacement Considerations
The TMUX1111PWR serves as a pin-compatible alternative utilizing a TSSOP-16 package. Verify that the larger package dimensions fit the available board space. Other family members like the TMUX1112 share similar electrical profiles but may differ in specific parameter tolerances or thermal characteristics.
