CD74FCT534ATQM

Overview

The CD74FCT534ATQM is an octal D-type flip-flop manufactured by Harris Corporation, belonging to the FCT logic series. It features positive-edge triggering and provides true outputs with three-state capability for bus-oriented memory register applications. The device is housed in a 20-pin SSOP package (0.154 inch width) and operates within a standard voltage range typical for CMOS logic. It supports bidirectional data transfer and includes independent output enable controls.

Feature Summary

• Octal D-type flip-flop architecture with positive-edge clock triggering
• Three-state outputs for efficient bus-driven system designs
• True output polarity maintaining input data state at the clock edge
• CMOS construction ensuring low power consumption and high noise immunity

Applications

• Bus-oriented memory register implementations
• Two-place storage elements in digital systems
• Portable battery-operated equipment requiring low power
• High-speed data latching in microprocessor interfaces

Procurement Notes

Verify component authenticity through authorized Harris Corporation distributors or certified suppliers. Confirm that the received units match the specified 20-SSOP package dimensions and pinout configuration. Check for manufacturing date codes and lot traceability to ensure compliance with quality standards. Ensure handling procedures account for electrostatic discharge sensitivity inherent to CMOS technology.

Selection Notes

Select this component when designing systems requiring octal data storage with tri-state bus compatibility. Consider the FCT series speed and power characteristics relative to alternative logic families. Evaluate the SSOP package constraints against PCB layout requirements. Verify that the operating temperature range meets the environmental conditions of the target application.
