CY74FCT2244CTQCT

Overview

The CY74FCT2244CTQCT is an octal buffer and line driver manufactured by Texas Instruments, belonging to the FCT logic series. It features eight non-inverting inputs and three-state outputs housed in a QSOP-20 package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a propagation delay of 4.1 ns at 5 V, high-level output current of -15 mA, low-level output current of 12 mA, and static current of 100 nA. It supports surface mount installation and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides buffering and line driving capabilities for digital signals with non-inverting logic functionality.
• Integrates three-state output control to facilitate bus-oriented architectures and system isolation.
• Utilizes CMOS technology within the FCT series to ensure compatibility with TTL input levels.

Applications

• Bus-oriented systems requiring signal buffering
• Memory address drivers
• Clock drivers

Procurement Notes

Verify the specific suffix 'CTQC' against the manufacturer's official datasheet to confirm the exact tape and reel quantity or packaging variant. Ensure the component meets RoHS compliance requirements as specified in the latest documentation. Cross-reference the ordering number with authorized distributors to validate authenticity and traceability before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits that require octal buffering with three-state capability. It is suitable for applications needing fast switching speeds indicated by the 4.1 ns propagation delay. Consider the QSOP-20 package constraints and the 5V operating voltage range during schematic capture and PCB layout planning.

Part Context

This part belongs to the CY74FCT2244T family of octal buffers and line drivers. It shares functional similarities with other devices in the FCT series but is distinct due to its specific pinout and three-state output configuration. The component serves as a standard solution for interfacing between different logic families or driving heavy loads on data buses.

Replacement Considerations

The CY74FCT2244CTQCTG4 is a confirmed substitute part number within the same product family. Verify pin compatibility and electrical specifications before implementation.
