TMUX6213RUMR

Overview

The TMUX6213RUMR is a precision analog switch featuring four independently selectable 1:1 single-pole, single-throw (SPST) channels in a 16-pin WQFN package. It operates on single supplies from 4.5V to 36V, dual supplies from ±4.5V to ±18V, or asymmetric configurations. The device supports bidirectional analog and digital signals ranging from VSS to VDD with low on-resistance of 2Ω typical at 25°C under ±15V supply. Logic control inputs are compatible with 1.8V logic levels and include integrated pull-down resistors. The component provides high current support up to 330mA maximum in the WQFN package and functions reliably across an operating temperature range of –40°C to +125°C.

Feature Summary

• Supports rail-to-rail signal transmission across wide voltage ranges
• Features fail-safe logic for protection against undefined states
• Includes integrated pull-down resistors on all logic pins

Applications

• Sample-and-hold circuits
• Feedback gain switching
• Signal isolation
• Data acquisition systems (DAQ)
• Patient monitoring and diagnostics

Procurement Notes

Verify the specific ordering suffix RUM corresponds to the 16-pin WQFN package configuration required for your design. Confirm that the logic control requirements align with the Logic Low + Logic High functionality unique to the TMUX6213 variant within the family. Ensure thermal management strategies account for the specified power dissipation limits in the target application environment.

Selection Notes

Select the TMUX6213RUMR when simultaneous break-before-make timing is required between channels, as this feature is exclusive to the TMUX6213 model compared to the TMUX6211 and TMUX6212 variants. Verify that the 1.8V logic compatibility meets the interface requirements of the controlling microcontroller or processor without needing external level shifting circuitry.

Part Context

This component belongs to the Texas Instruments TMUX621x family of precision switches, which also includes the TMUX6211 and TMUX6212 models. While sharing similar electrical characteristics and package options, the TMUX6213 is distinguished by its specific logic control configuration supporting both Logic Low and Logic High states, enabling distinct channel activation behaviors compared to its siblings.

Replacement Considerations

Direct functional substitutes within the same family include the TMUX6211RUMR and TMUX6212RUMR, though they lack the combined Logic Low/High control capability of the TMUX6213.
