74HCT377D-Q100J

Overview

The Nexperia 74HCT377D-Q100J is an automotive-grade octal D-type flip-flop with positive-edge triggering, certified to AEC-Q100 standards. It operates within a supply voltage range of 4.5V to 5.5V and features non-inverting outputs. The device supports clock frequencies up to 53 MHz and exhibits a maximum propagation delay of 32ns at 4.5V with 50pF load. It draws a static current of 8µA and provides output currents of 4mA (high) and 5.2mA (low). Designed for surface mount assembly, it is housed in a 20-SOIC package and functions reliably across an ambient temperature range of -40°C to +125°C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards for enhanced reliability
• Octal D-type flip-flop architecture providing eight independent data storage elements
• Positive-edge triggered operation ensuring precise synchronous data capture
• Wide operating temperature range suitable for demanding automotive environments

Applications

• Automotive electronic control units requiring robust data latching
• Industrial systems utilizing high-temperature logic interfaces
• Data acquisition modules needing synchronized signal storage

Procurement Notes

Verify the specific suffix and manufacturer documentation to confirm AEC-Q100 certification status and exact package dimensions. Ensure compatibility with existing board layouts regarding the 20-SOIC footprint and thermal requirements. Cross-reference official datasheets for precise electrical characteristics under varying load conditions before finalizing procurement specifications.

Selection Notes

Select this component when automotive reliability and wide temperature tolerance are required for octal data storage. Compare against standard commercial variants if AEC-Q100 certification is not mandatory. Consider the 20-SOIC package constraints and ensure the 4.5V to 5.5V supply range aligns with the system power architecture. Evaluate propagation delay limits against the target clock frequency requirements.

Part Context

This part belongs to the 74HCT series of high-speed CMOS logic devices manufactured by Nexperia. The HCT technology ensures TTL-compatible input levels while maintaining CMOS performance benefits. The Q100 designation indicates adherence to automotive quality standards, distinguishing it from general-purpose industrial counterparts within the broader 74HCT family.

Replacement Considerations

The 74HCT377PW-Q100J serves as a parameter-equivalent alternative offered by Nexperia. Verify pinout compatibility and package differences between SOIC and TSSOP formats during substitution planning.
