Overview
The TMUX1511PWR is a Texas Instruments analog switch IC featuring four independent single-pole single-throw (SPST) channels in a TSSOP-14 package. It operates on a single supply voltage ranging from 1.5 V to 5.5 V with a maximum quiescent current of 70 µA. The device supports bidirectional analog and digital signals, handling input/output voltages up to 5.5 V. Key electrical parameters include a maximum on-resistance of 13 Ohms, a maximum propagation delay of 60 µs, and a maximum break-before-make time of 4 µs. It functions within an extended temperature range of -40°C to +125°C.
Feature Summary
- Four-channel SPST configuration for independent signal routing
- Wide single-supply operation compatible with low-voltage systems
- Bidirectional signal transmission capability
- Extended industrial temperature rating
Applications
- Server and communication equipment signal switching
- Industrial control system I/O multiplexing
- Portable instrumentation signal path selection
Procurement Notes
Verify the specific suffix PWR indicates the TSSOP-14 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the ordering part number matches the required pin count and thermal specifications for the target PCB layout.
Selection Notes
Select this component when four independent SPST switches are required in a surface-mount TSSOP-14 footprint. Compare the 13 Ohm on-resistance against lower-resistance alternatives if signal integrity is critical. Verify that the 1.5 V minimum operating voltage aligns with the system power rails and that the 5.5 V absolute maximum rating accommodates all signal levels.
Part Context
This device belongs to the TMUX1511 family of CMOS analog switches. While the base model shares core functionality, the PWR suffix specifically denotes the TSSOP-14 package option. Other variants in the series may offer different packages like UQFN-16 or distinct on-resistance characteristics, necessitating careful verification of the full part number for mechanical compatibility.
Replacement Considerations
Direct substitutes include other TMUX1511 variants such as TMUX1511RSVR, which offers a UQFN-16 package with lower on-resistance. Cross-reference pinouts and package dimensions carefully when replacing the TSSOP-14 version with alternative packages.
