74HCT273D,653

Overview

The Nexperia 74HCT273D,653 is an octal positive-edge triggered D-type flip-flop with master reset. It operates within a supply voltage range of 4.5V to 5.5V and features TTL-compatible input levels. The device provides non-inverting outputs with push-pull drive capabilities, delivering 4mA high-level and 5.2mA low-level output currents. It exhibits a maximum propagation delay of 30ns at 4.5V with 50pF load and a static current of 8µA. Designed for automotive applications, it holds AEC-Q100 qualification and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Octal configuration providing eight independent positive-edge triggered D-type flip-flops sharing a common clock and master reset.

Applications

• Automotive data storage systems requiring AEC-Q100 qualified components
• Parallel-to-serial conversion circuits utilizing the shift register functionality
• High-speed digital buffering and latching in industrial control environments

Procurement Notes

Verify the specific suffix '653' corresponds to the SO20 package variant when sourcing. Confirm AEC-Q100 automotive grade status is required for the target application. Check RoHS3 compliance documentation for environmental regulations. Ensure the distributor source matches the official Nexperia manufacturing origin to guarantee authenticity.

Selection Notes

Select this component for designs requiring eight synchronized data storage elements with a single clock signal. The HCT logic family ensures compatibility with standard TTL interfaces while maintaining CMOS power efficiency. Consider the 20-SOIC package dimensions for PCB layout constraints and thermal management requirements in dense assemblies.

Part Context

This part belongs to the Nexperia 74HCT series of high-speed CMOS logic devices. It functions as an octal flip-flop within the broader 74xx logic ecosystem. The device integrates eight D-type flip-flops into a single integrated circuit, offering a compact solution for parallel data retention and synchronization in complex digital logic architectures.

Replacement Considerations

Cross-reference with other manufacturers offering equivalent octal D-type flip-flops with reset functionality. Verify pinout compatibility and electrical specifications match before substitution. Ensure the alternative component meets the same AEC-Q100 automotive qualification standards if applicable.
