Overview
The TMUX1113PWR is a precision analog switch integrated circuit manufactured by Texas Instruments. It features four independent single-pole single-throw (SPST) switches 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 a maximum power supply current of 1 uA. The component supports a maximum DC switch current of 30 mA and functions reliably across an operating temperature range of -40°C to +125°C. It is housed in a TSSOP-16 surface-mount package.
Feature Summary
- Four independent SPST channels for precise signal routing
- Ultra-low power consumption with 1 uA maximum supply current
- Low on-state resistance of 4.9 Ohms for minimal signal loss
- Wide single-supply voltage operation from 1.08 V to 5.5 V
Applications
- Portable medical equipment requiring low power and high precision
- Industrial data acquisition systems
- Battery-powered instrumentation
- Signal conditioning circuits in harsh environments
Procurement Notes
Verify the specific ordering suffix PWR to confirm the TSSOP-16 package type and reel packaging configuration. Ensure compatibility with standard surface-mount assembly processes. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated products.
Selection Notes
Select this component when four isolated SPST switches are required in a compact footprint. The low on-resistance and wide voltage range make it suitable for precision applications. Consider the TSSOP-16 package constraints regarding thermal dissipation and board space availability during layout design.
Part Context
This part belongs to the TMUX111x family of precision CMOS analog switches. The family shares similar electrical characteristics but varies in pin count and configuration. The TMUX1113 specifically provides four SPST channels, distinguishing it from other variants like the TMUX1112 or TMUX1134 which may offer different channel counts or configurations.
Replacement Considerations
Direct replacements within the same family include TMUX1112RSVR and TMUX1113RSVR, noting differences in package type (UQFN vs TSSOP). Verify pinout compatibility and package dimensions before substituting to ensure mechanical fit.
