74HCT273D-Q100J

Overview

The Nexperia 74HCT273D-Q100J is an octal D-type flip-flop with master reset, designed for automotive applications. It operates within a supply voltage range of 4.5V to 5.5V and features positive-edge triggering. The device provides non-inverting outputs and includes a master reset input that forces outputs low independently of clock and data inputs. It is housed in a SOIC-20 package and complies with AEC-Q100 standards for grade qualification.

Feature Summary

• Octal configuration with eight positive-edge triggered D-type flip-flops
• Master reset input forces all outputs low regardless of clock or data states
• Compliant with AEC-Q100 automotive reliability standards
• Inputs include clamp diodes for high-voltage interface capability

Applications

• Automotive data storage systems
• Vehicle control unit interfaces
• Digital signal latching in automotive networks

Procurement Notes

Verify the specific suffix and package variant against the official Nexperia datasheet to ensure compatibility with design requirements. Confirm AEC-Q100 qualification status and operating temperature range specifications before integration. Cross-reference ordering information with authorized distributors to avoid counterfeit components and ensure traceability.

Selection Notes

Select this component when an octal register with synchronous data capture and asynchronous reset is required in automotive environments. Ensure the logic family matches the system voltage levels, as HCT series requires 5V operation. Consider the SOIC-20 package constraints for PCB layout and thermal management during the design phase.

Part Context

This part belongs to the Nexperia 74HCT273-Q100 family of automotive-grade logic devices. It is specifically engineered for robust performance in harsh automotive electrical environments. The device serves as a fundamental building block for sequential logic circuits requiring multiple bit storage with centralized reset functionality.

Replacement Considerations

Direct substitutes include other 74HCT273 variants from different manufacturers that meet AEC-Q100 standards. Verify pinout compatibility and electrical characteristics such as propagation delay and output drive current before substitution.
