74HCT7273D,118

Overview

The 74HCT7273D,118 is an octal D-type edge-triggered flip-flop manufactured by NXP Semiconductors. It operates within a supply voltage range of 4.5 V to 5.5 V and features single-ended inputs and outputs with non-inverting polarity. The device provides eight independent circuits in a SOT-163 (SOIC-20) surface-mount package. Key electrical specifications include a propagation delay of 16 ns and a low-level output current capability of 4 mA. It supports a wide operating temperature range from -40°C to +125°C.

Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops for parallel data storage.

Applications

• Parallel data storage in digital logic systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package and tape/reel specifications. Check for RoHS compliance status and ensure the part meets AEC-Q100 requirements if automotive qualification is necessary. Validate that the supplier provides valid traceability documentation.

Selection Notes

Select this component when an octal D-type edge-triggered flip-flop is required for 5V logic applications. Ensure the design accommodates the 16 ns propagation delay and 4 mA output drive capability. Verify that the SOIC-20 package fits the PCB layout constraints and thermal management requirements for the intended operating temperature range.

Part Context

This component belongs to the 74HCT logic family, designed for compatibility with standard TTL levels while utilizing CMOS technology. It serves as a fundamental building block for sequential logic circuits requiring multiple bits of storage. The device is distinct from transparent latches like the 74HCT573 series due to its edge-triggered operation mode.
