CY74FCT273TQCT

Overview

The CY74FCT273TQCT is an octal D-type flip-flop with a master clear input, manufactured by Texas Instruments. It belongs to the FCT logic series and features CMOS outputs with TTL-compatible inputs. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports surface-mount installation in a QSOP-20 package. It exhibits a propagation delay of 5.8 ns, with high-level output current capability of -32 mA and low-level output current of 64 mA. The component functions as a single circuit register and maintains non-inverting polarity across its eight channels.

Feature Summary

• Octal D-type flip-flop architecture with dedicated master clear functionality for synchronous data storage.

Applications

• General-purpose digital data storage applications requiring octal bit registers.

Procurement Notes

Verify that the specific suffix 'TQCT' corresponds to the QSOP-20 package and reel/cut-tape packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications. Ensure the manufacturer designation aligns with Texas Instruments documentation for this exact part number revision.

Selection Notes

Select this component when an octal D-type flip-flop with a master clear function is required in a QSOP-20 surface-mount package. The FCT series provides compatibility with TTL input levels while utilizing CMOS output characteristics. Consider the 5.8 ns propagation delay and 4.75 V to 5.25 V operating voltage range for system timing and power budget alignment.

Part Context

This component is part of the CY74FCT273T family of octal D-type flip-flops. It shares functional similarities with other devices in the FCT logic series, such as the CY74FCT273ATQCT and CD74FCT273E, differing primarily in package type, manufacturing revision, and specific electrical parameter tolerances defined by the manufacturer.
