74HCT273D,652

Overview

The 74HCT273D,652 is an octal D-type flip-flop manufactured by Nexperia USA Inc., belonging to the HCT logic family. It features a single positive-edge clock input and an active-low master reset. The device operates within a supply voltage range of 4.5 V to 5.5 V. It is housed in a 20-pin SOIC package with a width of 7.50 mm. The component supports surface mount installation and functions as a digital storage element for high-speed applications.

Feature Summary

• Octal configuration providing eight independent D-type flip-flops on a single chip
• Positive-edge triggered clocking mechanism for precise data synchronization
• Active-low master reset input for immediate asynchronous clearing of all outputs
• Non-inverting output structure compatible with standard logic interfacing

Applications

• High-speed parallel-to-serial conversion circuits
• Data buffering and temporary storage in digital systems
• Shift register implementations for signal processing
• Memory address latching in microcontroller interfaces

Procurement Notes

Verify the specific suffix 652 against official Nexperia documentation to confirm the exact tube packaging quantity and marking details. Ensure the procurement channel sources genuine components from authorized distributors to avoid counterfeit risks. Confirm that the required operating temperature range aligns with the specified industrial limits before finalizing orders.

Selection Notes

Select this component when designing systems requiring an octal register with TTL-compatible input levels. The HCT series ensures compatibility with 5 V CMOS logic while accepting standard TTL inputs. Consider the 20-SOIC package dimensions for PCB layout constraints. Verify that the maximum clock frequency requirements of the application fall within the device's specified operational limits.

Part Context

This part belongs to the 74HCT273 family of octal D-type flip-flops. It shares functional similarities with other members of the series but differs in package options and specific manufacturing revisions. The 74HCT273D,652 variant specifically denotes the SOIC-20 package configuration produced by Nexperia, distinguishing it from tape-and-reel or alternative housing versions.

Replacement Considerations

Publicly confirmed substitute part numbers include 74HCT273D,118 and 74HCT273PW,118. These alternatives offer equivalent electrical characteristics and pinout configurations. Verify package compatibility and lead time availability when transitioning between these specific Nexperia variants.
