CD74FCT2244CTQM

Overview

The CD74FCT2244CTQM is an octal buffer and line driver manufactured by Harris Corporation. It belongs to the FCT series of FAST CMOS logic devices. The component features eight non-inverting outputs with three-state capability, allowing for effective bus driving and signal buffering in digital systems. It operates within a supply voltage range of 1.65V to 5.5V and supports surface mount installation in a 20-pin QSOP package.

Feature Summary

• Octal configuration providing eight independent non-inverting buffer channels
• Three-state output design enabling efficient multi-driver bus architectures
• FAST CMOS technology ensuring high-speed performance with low power consumption

Applications

• High-speed data bus buffering in computer systems
• Clock distribution networks requiring signal integrity
• Memory interface circuits for address and data lines

Procurement Notes

Verify the manufacturer designation as Harris Corporation or its successor entities like L3Harris Technologies when sourcing this component. Confirm the specific suffix CTQM corresponds to the 20-pin QSOP package variant. Ensure compliance with relevant environmental standards if required by your application specifications.

Selection Notes

Select this device for applications requiring octal buffering with tri-state control. It is suitable for systems operating between 1.65V and 5.5V. Consider the QSOP package constraints for PCB layout. Compare propagation delays against system timing requirements to ensure adequate speed margins for your specific digital interface needs.

Part Context

This part is part of the CD74FCT2244 family of octal buffers. It shares functional similarities with other FCT series drivers but is distinct in its eight-channel configuration and specific package type. It serves as a critical interface component for managing multiple digital signals simultaneously in complex electronic designs.

Replacement Considerations

Check for equivalents from Texas Instruments such as the CY74FCT2244 series. Verify pin compatibility and electrical characteristics before substitution. Ensure the replacement maintains the same three-state functionality and voltage operating ranges.
