CD74FCT544ATM96

Overview

The CD74FCT544ATM96 is an octal buffer and line driver manufactured by Harris Corporation, belonging to the FCT logic series. It features a single functional block with eight bits per element and provides non-inverting true outputs. The device utilizes CMOS technology and is housed in a 24-pin Small Outline Integrated Circuit (SOIC) package. It operates within a supply voltage range of 4.75 V to 5.25 V and supports a wide operating temperature range from -40°C to 85°C. The output configuration includes three-state capability.

Feature Summary

• Provides non-inverting buffering for eight-bit data paths
• Features three-state outputs for bus-oriented applications
• Utilizes FCT series CMOS technology for high-speed performance

Applications

• Bus-oriented memory and register systems
• Clock drivers and buffer circuits
• High-density data acquisition systems

Procurement Notes

Verify the manufacturer designation as Harris Corporation or its successor entities, as corporate acquisitions may affect branding on legacy components. Confirm the specific suffix TM96 corresponds to the intended tape-and-reel packaging format if required for automated assembly processes. Ensure compatibility with RoHS regulations depending on the production date, as older Harris stock may not meet current environmental standards. Cross-reference the datasheet revision to confirm pinout consistency with design schematics.

Selection Notes

Select this component when an octal non-inverting buffer with three-state control is required for system buses. The FCT series offers faster switching speeds compared to standard HC or HCT logic families while maintaining CMOS power efficiency. The 24-SOIC package is suitable for surface-mount applications requiring moderate pin density. Consider the 4.75V to 5.25V operating range to ensure compatibility with standard 5V logic systems.

Part Context

This part belongs to the CD74FCT family of high-speed CMOS logic devices originally developed by Harris Semiconductor. The FCT series was designed to bridge the performance gap between TTL and standard CMOS technologies. Harris Corporation's logic division was later acquired by Texas Instruments, which continues to support and manufacture many of these legacy parts under the TI brand. The CD74 prefix indicates commercial temperature grade availability.

Replacement Considerations

The CD74FCT544ATM96 may be functionally replaced by the SN74FCT544ATM96 manufactured by Texas Instruments, following the acquisition of Harris Semiconductor's logic assets. Verify that the replacement source confirms the same 24-SOIC package and electrical characteristics. Other FCT-series buffers from different manufacturers should be evaluated for pinout and timing compatibility.
