Overview
The TMUX1111PWR is a precision analog switch IC from Texas Instruments, featuring four independent single-pole single-throw (SPST) channels in a TSSOP-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 µA. The device supports bidirectional analog and digital signals between ground and the supply rail, offering a maximum on-state resistance of 4.9 Ohms. Designed for low leakage applications, it exhibits an on-state leakage current of 3 pA. The component functions reliably across an extended temperature range from -40°C to +125°C.
Feature Summary
- Ultra-low on-state leakage current of 3 pA ensures minimal signal distortion in high-impedance circuits.
- Wide single-supply operating range from 1.08 V to 5.5 V accommodates various system power architectures.
- Low on-state resistance of 4.9 Ohms maximizes bandwidth and minimizes signal attenuation.
- Supports bidirectional signal flow between source and drain pins within the supply voltage range.
Applications
- Medical equipment requiring precise signal routing
- Industrial control systems with low-power constraints
- Data acquisition systems needing low-leakage switching
Procurement Notes
Verify the specific suffix 'PWR' corresponds to the TSSOP-16 package and tape-and-reel shipping configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ordering quantities align with standard reel sizes to avoid cut-tape premiums or minimum order discrepancies.
Selection Notes
Select this component when ultra-low leakage is critical for signal integrity. The 4-channel SPST configuration suits multiplexing tasks where independent channel control is required. Verify that the 4.9 Ohm on-resistance meets the application's voltage drop requirements at the maximum expected load current.
Part Context
This part belongs to the TMUX111x family of precision CMOS switches. Unlike higher-voltage variants such as the TMUX5411, this series is optimized for low-voltage, low-leakage performance. The PWR suffix specifically denotes the plastic small-outline package variant, distinguishing it from the smaller RSVR UQFN version.
Replacement Considerations
The TMUX1112RSVR offers identical electrical specifications but utilizes a UQFN-16 package instead of TSSOP-16. Designers must evaluate footprint compatibility and thermal dissipation differences when substituting packages within the same functional family.
