CD74FCT534CTM

Overview

The CD74FCT534CTM is a Fast Octal D Register manufactured by Harris Corporation, designed for high-speed digital logic applications. It features a single D-type flip-flop element with 8-bit width and positive edge triggering. The device operates within a supply voltage range of 4.75V to 5.25V and has a quiescent current of 500 µA. It is housed in a 20-SOIC package with a width of 0.295 inches (7.50mm). The component supports an operating temperature range from -40°C to 85°C.

Feature Summary

• Octal D-register configuration with positive edge triggering
• Fast CMOS technology for high-speed digital logic
• Single function unit with 8-bit data width

Applications

• High-speed digital logic systems
• Data storage and transfer registers
• Parallel-to-serial conversion circuits

Procurement Notes

Verify the manufacturer designation as Harris Corporation or its successors, noting that Harris Corporation's semiconductor assets were acquired by Intersil and subsequently Renesas. Confirm the specific suffix 'CTM' corresponds to the 20-SOIC package variant. Ensure compatibility with the specified 4.75V to 5.25V supply range and check for any RoHS compliance status changes due to corporate acquisitions.

Selection Notes

Select this component when an octal D-register with fast switching speeds is required for 8-bit parallel data handling. The positive edge trigger characteristic suits synchronous designs. Consider the 20-SOIC package constraints for PCB layout. Verify that the 500 µA quiescent current meets power budget requirements for the target application environment.

Part Context

This part belongs to the FCT series of Fast CMOS logic devices produced by Harris Corporation. The FCT line was known for combining CMOS low power consumption with TTL-compatible speed. The CD74FCT534CTM specifically implements an octal D-register function, differing from bus drivers or inverters in the same family by providing registered storage rather than simple signal transmission.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the acquisition of Harris Semiconductor assets, equivalent parts may be sourced from Renesas or Intersil product lines. Verify pinout and electrical specifications before substitution.
