74HCT574DB,118

Overview

The Nexperia 74HCT574DB,118 is an octal D-type flip-flop with 3-state outputs belonging to the HCT logic family. It operates on a single supply voltage ranging from 4.5 V to 5.5 V and features a maximum propagation delay of 26 ns at 5 V with 50 pF load. The device provides push-pull outputs capable of sourcing and sinking 6 mA each, with a static current of 8 µA. It is housed in a 20-pin SO package (SOT163) designed for surface mount installation.

Feature Summary

Octal D-type flip-flop architecture with positive-edge triggering
Three-state non-inverting outputs suitable for bus-oriented applications
TTL-compatible input levels ensuring interface compatibility with standard TTL devices

Applications

Parallel-to-serial data conversion circuits
Bus-oriented memory register implementations
Input/output port expansion for microprocessor systems

Procurement Notes

Verify the specific suffix 'DB' against official Nexperia documentation to confirm the SOIC-20 package variant. Ensure the ordering code matches the exact manufacturer part number to avoid confusion with similar series components. Confirm RoHS compliance status through the latest product discontinuation notices or environmental declarations provided by the supplier.

Selection Notes

Select this component when TTL-level inputs are required alongside high-speed octal storage capabilities. The HCT series ensures direct compatibility with standard TTL logic families while offering improved noise immunity compared to older LS variants. Consider the 20-pin SO package constraints regarding board space and thermal dissipation requirements for the target application environment.

Part Context

This component belongs to the 74HCT574 family of octal D-type flip-flops manufactured by Nexperia. It serves as a digital storage element within the broader 74-series logic ecosystem. The device is distinct from transparent latches like the 74HCT573 due to its edge-triggered operation mode rather than level-sensitive transparency.
