TMUX8213RUMR

Overview

The TMUX8213RUMR is a high-voltage analog switch IC featuring four independently controllable 1:1 single-pole single-throw (SPST) channels. It supports dual supplies from ±10 V to ±50 V, asymmetric configurations, and single supplies up to 100 V. The device offers a maximum on-resistance of 10 Ω, low crosstalk of -110 dB, and input leakage of 10 pA. Logic inputs support 1.8-V, 3.3-V, and 5-V levels with fail-safe operation up to 48 V. It operates within an ambient temperature range of -40°C to +125°C and is housed in a 16-pin WQFN package.

Feature Summary

• High voltage capability supporting up to 100 V single supply or ±50 V dual supply
• Latch-up immunity for reliable operation in harsh environments
• Fail-safe logic allowing control voltages up to 48 V independent of power rails
• Bidirectional signal path with low on-resistance flatness

Applications

• Semiconductor test equipment
• LCD test equipment
• Battery test equipment
• Data acquisition systems (DAQ)
• Programmable logic controllers (PLC)

Procurement Notes

Verify the specific suffix RUM corresponds to the WQFN-16 package configuration before ordering. Confirm that the logic control requirements align with the TMUX8213 variant, which supports both logic high and logic low activation states. Ensure supply voltage differentials remain within the specified 10 V to 100 V range during system design.

Selection Notes

Select the TMUX8213RUMR when bidirectional switching and high voltage isolation are required. The device is suitable for applications needing consistent parametric performance across wide supply ranges. Consider thermal dissipation limits if operating at elevated temperatures or high continuous currents. Verify compatibility with existing logic levels, as the device supports 1.8-V inputs without additional level shifting.

Part Context

The TMUX8213RUMR belongs to the TMUX821x family of high-voltage analog switches manufactured by Texas Instruments. This family includes the TMUX8211 and TMUX8212, which differ primarily in logic activation states. The TMUX8213 specifically supports both logic high and logic low control inputs, providing greater flexibility in system integration compared to the other variants in the series.

Replacement Considerations

Direct replacements within the same family include the TMUX8211RUMR and TMUX8212RUMR, though these have different logic activation requirements. Cross-family alternatives may require verification of pin compatibility and voltage ratings.
