74AHCT273BQ-Q100X

Overview

The Nexperia 74AHCT273BQ-Q100X is an automotive-grade D-type flip-flop featuring eight bits with positive-edge triggering. It operates within a supply voltage range of 4.5V to 5.5V and supports a maximum clock frequency of 75 MHz. The device exhibits a typical propagation delay of 9.2ns at 5V with 50pF load, while maintaining a static current consumption of only 4µA. Designed for robust performance, it offers symmetrical output drive capabilities of 8mA for both high and low states. The component is housed in a compact 20-DHVQFN package (4.5x2.5mm) with exposed pad, ensuring efficient thermal dissipation and minimal PCB footprint for space-constrained applications.

Feature Summary

Procurement Notes

Verify the specific suffix Q100X against official Nexperia documentation to confirm exact tape-and-reel specifications and moisture sensitivity level. Ensure compatibility with DHVQFN-20 soldering profiles during assembly. Cross-reference the manufacturer part number 935300187115 for accurate inventory tracking. Confirm that the selected distributor provides genuine Nexperia products with full traceability. Validate that the component meets the required AEC-Q100 Grade 1 temperature range specifications for your target application environment.

Selection Notes

Select this component when designing circuits that require automotive-certified digital storage with precise timing control. The AHCT series ensures TTL-compatible input levels, simplifying integration with legacy 5V logic families. Consider the 20-DHVQFN package for applications prioritizing small form factors and improved thermal performance over traditional leaded packages. Evaluate the 8mA output drive strength against load requirements to ensure signal integrity without additional buffering. Verify that the 4.5V to 5.5V operating range aligns with your system's power supply architecture.

Part Context

This device belongs to Nexperia’s advanced high-speed CMOS (AHCT) logic family, specifically designed for automotive and industrial applications. The 74AHCT273 variant serves as an octal D-type flip-flop, providing parallel-to-serial conversion capabilities or temporary data storage. As part of the broader 74-series ecosystem, it maintains pin-out compatibility with standard logic functions while offering enhanced speed and lower power consumption compared to older HC series counterparts. The Q100 designation signifies its qualification for harsh automotive environments.

Replacement Considerations

The 74AHCT273BQ,115 is a documented equivalent part number from Nexperia sharing identical logical function and electrical characteristics. Both variants utilize the same 20-DHVQFN package and support AEC-Q100 Grade 1 qualification. Designers may substitute one for the other provided that manufacturing lot dates and specific packaging variations are reconciled. Always verify the latest datasheet revisions to ensure no changes in mechanical dimensions or thermal properties affect the existing board layout.
