74AHC273PW-Q100J

Overview

The 74AHC273PW-Q100J is an octal D-type flip-flop with a separate clock input, manufactured by Nexperia. It belongs to the AHC logic family and is housed in a TSSOP-20 package (SOT360). The component is qualified under the AEC-Q100 standard for automotive applications. It operates within a supply voltage range of 2.0 V to 5.5 V and supports data rates up to 180 MHz. The device features high noise immunity, low power dissipation, and overvoltage tolerant inputs.

Feature Summary

• Octal D-type flip-flop architecture with a single clock input for simultaneous data capture
• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Overvoltage tolerant inputs allowing interface with voltages exceeding VCC
• High noise immunity and CMOS low power dissipation characteristics

Applications

• Automotive electronic control units requiring robust data storage
• Industrial systems utilizing mixed voltage environments
• General-purpose digital signal processing and buffering circuits

Procurement Notes

Verify the specific suffix J indicates tape and reel packaging configuration. Confirm AEC-Q100 Grade 1 qualification status matches project requirements. Ensure the TSSOP-20 footprint aligns with PCB layout constraints. Cross-reference the manufacturer part number with official Nexperia documentation to validate authenticity and revision level before procurement.

Selection Notes

Select this component when an octal storage element is required for automotive or industrial designs. The AHC series offers superior speed compared to HC while maintaining low power consumption. The wide supply voltage range facilitates integration into systems operating between 2.0 V and 5.5 V. Consider the TSSOP-20 package for compact surface-mount assembly needs.

Part Context

This part is part of Nexperia's extensive portfolio of automotive-grade logic ICs. It complements other components in the 74AHC series, such as gates and buffers, enabling complete digital logic solutions. The Q100 designation signifies its suitability for harsh automotive environments, distinguishing it from standard commercial grade counterparts.

Replacement Considerations

Direct replacements include the 74AHC273D-Q100J, which shares identical electrical specifications but utilizes a SOIC-20 package instead of TSSOP-20. Designers must verify pinout compatibility and thermal performance differences between the two package types during substitution.
