TMUX6212PWR

Overview

The TMUX6212PWR is a four-channel analog switch IC from Texas Instruments, featuring a 4 x SPST configuration in a TSSOP-16 package. It operates on a single supply voltage ranging from 4.5 V to 36 V or dual supplies of ±4.5 V to ±18 V. The device supports bidirectional analog and digital signals across the full supply range. Key electrical parameters include a maximum on-resistance of 3.1 Ohms, a maximum propagation delay of 180 ns, and a maximum off-time of 200 ns. It functions within a temperature range of -40°C to +125°C with a maximum power dissipation of 700 mW.

Feature Summary

• Supports wide single and dual supply voltages for flexible system integration
• Features low on-resistance to minimize signal loss during transmission
• Includes integrated pull-down resistors on logic inputs to prevent floating states
• Offers fault-safe logic allowing control input protection without power

Applications

• Data acquisition systems requiring precise signal routing
• Industrial process control and programmable logic controllers
• Medical equipment such as patient monitors and ultrasound scanners
• Test and measurement instruments including oscilloscopes and analyzers

Procurement Notes

Verify the specific suffix PWR indicates the TSSOP-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the ordering part number matches the required channel count and logic compatibility specifications for the target design.

Selection Notes

Select this model over TMUX6211PWR if high-level logic control is preferred, as TMUX6212 activates with a logic high input. Choose the TSSOP-16 package for through-hole compatible surface mount assembly. Verify that the 3.1 Ohm on-resistance meets the signal integrity requirements compared to lower resistance alternatives in the same family.

Part Context

This component belongs to the TMUX621x series of precision analog switches designed for industrial and medical applications. It shares core architectural features with TMUX6211 and TMUX6213 but differs in logic activation polarity. The series utilizes SOI technology to provide latch-up immunity and robust performance across extended temperature ranges.

Replacement Considerations

TMUX6211PWR serves as a logical alternative with identical electrical characteristics but activates via logic low instead of logic high. Designers must verify logic level compatibility when substituting between these variants to ensure correct switching behavior.
