CD74FCT273ATM

Overview

The CD74FCT273ATM is an octal D-type flip-flop from the FCT series, manufactured by Harris Corporation. It features eight positive-edge-triggered D flip-flops with true outputs in a 20-pin PDSO (SOIC) package. The device operates on CMOS technology with TTL-compatible inputs. Key electrical parameters include a maximum low-level output current of 48 mA and a load capacitance of 50 pF. It supports an operating temperature range from -40 °C to 85 °C.

Feature Summary

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

Applications

• Parallel data register applications requiring high-speed CMOS logic.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Ensure the specific suffix matches required packaging and temperature grades. Validate pinout compatibility with existing PCB layouts before procurement.

Selection Notes

Select this component for designs requiring octal storage with TTL input compatibility. Consider the SOIC-20 package constraints for board space. Verify that the 48 mA sink capability meets system drive requirements. Check thermal limits against expected ambient conditions.

Part Context

This part belongs to the Harris FCT logic family, designed for high-speed CMOS applications. It serves as a standard octal register solution within the company's portfolio of digital logic integrated circuits.

Replacement Considerations

Check Texas Instruments CY74FCT273 variants for potential cross-reference options if Harris supply is unavailable. Verify functional equivalence regarding pinout and electrical characteristics before substitution.
