SN74AC04WBQARQ1

Overview

The SN74AC04WBQARQ1 is an automotive-grade hex Schmitt-trigger inverter from Texas Instruments, designed for high reliability in demanding environments. It operates within a supply voltage range of 2V to 6V and accepts input voltages up to 6V. The device features a maximum propagation delay of 7ns at 5V and supports an operating temperature range from -40°C to +125°C. Packaged in a 14-pin WQFN (BQA) format measuring 3.00mm by 2.50mm, it includes six independent inverters performing the Boolean function Y = A.

Feature Summary

• Qualified for automotive applications with extended temperature capabilities
• Schmitt-trigger inputs provide different threshold levels for positive-going and negative-going signals
• Balanced CMOS push-pull outputs capable of sinking and sourcing similar currents
• Inputs accept TTL-voltage compatible levels allowing voltage translation

Applications

• Synchronize inverted clock inputs
• Debounce a switch
• Invert a digital signal

Procurement Notes

Verify that the specific BQA package variant matches the required footprint dimensions of 3.00mm x 2.50mm. Confirm the Q-suffix designation aligns with the intended operating temperature range of -40°C to +125°C. Ensure ESD precautions are observed during handling as specified in the datasheet. Check for any recent documentation updates regarding material or assembly changes.

Selection Notes

Select this component when a hex inverter with Schmitt-trigger action is required for noise immunity in automotive systems. It is suitable for applications needing voltage translation between 3.3V and 5V logic levels. Consider the WQFN package for space-constrained designs requiring thermal dissipation through the exposed pad. Verify that the 7ns propagation delay meets the timing requirements of the target circuit.

Part Context

This part belongs to the SN74AC04-Q1 family of automotive logic devices. It is distinct from standard catalog versions by its qualification for automotive use and specific packaging options. The device implements the classic 74AC04 hex inverter function but incorporates Schmitt triggers for improved signal integrity compared to conventional inverters.

Replacement Considerations

SN74AC04QPWRQ1 is a verified alternative offering the same functionality in a TSSOP-14 package.
