74AHCT273PW-Q100J

Overview

The Nexperia 74AHCT273PW-Q100J is an automotive-grade, 8-bit D-type flip-flop with positive-edge triggering and a master reset. It belongs to the 74AHCT logic family, ensuring CMOS compatibility with TTL inputs. The device operates within a supply voltage range of 4.5V to 5.5V and supports clock frequencies up to 36 MHz. Key electrical parameters include a maximum propagation delay of 30ns at 4.5V with 50pF load, static current of 8µA, and output drive capabilities of 4mA high and 5.2mA low. It features an input capacitance of 3.5 pF and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for extended reliability.
• Positive-edge triggered D-type architecture with dedicated master reset functionality.
• CMOS technology providing full compatibility with standard TTL input levels.

Applications

• Data storage registers in automotive electronic control units.
• Shift register configurations for display or indicator drivers.
• Parallel-to-serial data conversion circuits in vehicle communication systems.

Procurement Notes

Verify component authenticity through authorized Nexperia distributors or certified partners. Confirm that the specific suffix matches the required TSSOP-20 package variant. Ensure compliance with RoHS3 directives and REACH regulations prior to integration. Cross-reference the manufacturer part number against official Nexperia documentation to validate revision history and quality certifications before final procurement decisions.

Selection Notes

Select this component when designing automotive logic circuits requiring robust performance under wide temperature variations. The AHCT series is appropriate for systems interfacing directly with TTL sources without additional level shifting. Consider the 36 MHz clock limit and 30ns propagation delay for timing-critical applications. The TSSOP-20 package offers surface-mount convenience suitable for compact automotive PCB layouts.

Part Context

This device is part of Nexperia's extensive portfolio of automotive-qualified logic integrated circuits. It shares functional similarities with other 8-bit flip-flops in the 74HCT and 74AHCT families but distinguishes itself through specific AEC-Q100 certification and optimized speed-power characteristics. The PW suffix indicates the TSSOP-20 housing, differentiating it from other package options like QFN or SOIC variants within the same logical function family.
