Overview
The TMUX1113RSVR is a precision analog switch integrated circuit manufactured by Texas Instruments. It features four independent single-pole single-throw (SPST) channels within a single package. The device operates on a single supply voltage ranging from 1.08 V to 5.5 V. Key electrical specifications include a maximum on-state resistance of 4.9 Ohms and an extremely low on-state leakage current of 3 pA. The component supports bidirectional signal transmission between source and drain pins, covering the full ground-to-supply range. It is housed in a 16-pin Ultra Small Quad Flatpack (UQFN) package with a 2 mm x 2 mm footprint.
Feature Summary
- Ultra-low on-state leakage current for high-precision signal integrity
- Wide single-supply operating voltage range suitable for low-power applications
- Compact surface-mount packaging designed for space-constrained designs
Applications
- Portable medical equipment requiring minimal power consumption
- Industrial data acquisition systems needing precise signal switching
- Automotive sensor interfaces demanding reliability across temperature ranges
Procurement Notes
Verify the specific suffix RSVR corresponds to the UQFN-16 package and reel packaging configuration before ordering. Confirm that the 1.08 V minimum operating voltage aligns with your system's power rail capabilities. Ensure ESD protection measures are implemented during handling due to the sensitive CMOS input structure.
Selection Notes
Select this component when four independent SPST switches are required in a minimal footprint. Compare against the TMUX1113PWR if a TSSOP-16 package is preferred over the UQFN-16 form factor. Consider the TMUX1109 series if multiplexing functionality with fewer channels is sufficient for the application design.
Part Context
This part belongs to the TMUX111x family of precision analog switches from Texas Instruments. The family is characterized by its ultra-low leakage and wide voltage operation. The TMUX1113RSVR specifically denotes the four-channel SPST variant in the small UQFN package, distinguishing it from multiplexer variants or other package options within the same product line.
Replacement Considerations
The TMUX1113PWR serves as a pin-compatible alternative offering the same electrical characteristics but utilizes a TSSOP-16 package instead of the UQFN-16. Designers must verify board space constraints and thermal requirements when substituting between these package types.
