TMUX7413FRRPR

Overview

The TMUX7413FRRPR is a quad single-pole single-throw (SPST) analog switch from Texas Instruments, housed in a 16-pin WQFN package. It supports a single supply voltage range of 8 V to 44 V and dual supplies from ±5 V to ±22 V. The device features integrated fault protection capable of withstanding ±60 V overvoltage on source pins relative to ground, and up to ±85 V relative to the power supplies. It includes an active-low interrupt flag for fault status indication. Electrical characteristics include a typical on-resistance of 8.3 Ω, a maximum turn-on time of 930 ns, and a maximum turn-off time of 230 ns. The component operates within an ambient temperature range of -40°C to +125°C.

Feature Summary

• Integrated overvoltage protection on source pins handles faults up to ±60 V relative to ground and ±85 V relative to supplies.
• Active-low interrupt flag output indicates when any channel experiences an overvoltage condition.
• Fail-safe logic allows control signals up to 44 V independent of the power supply voltage.
• Latch-up immunity ensures robust operation under electrostatic discharge conditions.

Applications

• Factory automation and control systems
• Programmable logic controllers (PLC)
• Analog input modules
• Semiconductor test equipment
• Data acquisition systems (DAQ)

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current orderable addendum to confirm the package type and tape-and-reel specifications. Ensure that the selected variant matches the required thermal performance and pin configuration for the target PCB layout. Cross-reference the datasheet revision history to confirm the document status is Production Data rather than Advanced Information or Preview.

Selection Notes

Select the TMUX7413FRRPR when a break-before-make switching action is required among the TMUX741xF family. This specific model activates channels based on both high and low logic levels on the SEL pins. Verify that the application requires four independent SPST switches with fault protection. Confirm that the system can accommodate the 16-pin WQFN footprint and associated thermal dissipation requirements.

Part Context

This component belongs to the TMUX741xF series of fault-protected analog switches. It shares the same core architecture and protection features as the TMUX7411F and TMUX7412F. The primary distinction lies in the logic control scheme; the TMUX7413F utilizes both high and low logic states for channel selection, whereas the other variants use only one polarity. All devices in this series offer identical electrical performance regarding resistance, leakage, and bandwidth.

Replacement Considerations

The TMUX7411FRRPR and TMUX7412FRRPR are direct functional substitutes within the same package. They share identical pinouts and electrical ratings but differ in logic activation requirements. Ensure the control circuitry aligns with the specific logic state requirements of the replacement part.

FAQ

How does the TMUX7413F handle overvoltage conditions?

When the source pin voltage exceeds the supply voltage by a threshold, the channel turns off automatically. The drain pin becomes floating during the fault, and the FF pin asserts low to indicate the error.

What is the function of the FF pin?

The FF pin is an open-drain output that provides an active-low interrupt flag. It signals when any of the source inputs experience an overvoltage fault condition.

Can the TMUX7413F operate without power supplies?

Yes, the device offers powered-off protection. In the absence of power supplies, the channels remain in the OFF state regardless of the logic input conditions.
