Overview
The CD74FCT244CTQM is an octal buffer and line driver manufactured by Harris Corporation, belonging to the FCT logic series. It features eight non-inverting inputs with three-state outputs housed in a 20-pin QSOP package. The device operates on a supply voltage range of 1.65V to 5.5V and supports an operating temperature range from -40°C to 125°C. Key electrical characteristics include a high-level output current of -32 mA and a low-level output current of 64 mA. Propagation delay is specified at 4.6 ns at 5 V.
Feature Summary
- Provides eight non-inverting signal paths for bus driving applications
- Features three-state outputs to facilitate bus line management
- Supports wide supply voltage operation from 1.65V to 5.5V
- Designed for extended industrial temperature ranges up to 125°C
Applications
- Bus-oriented memory and address drivers
- Clock drivers and buffer circuits
- Multiplexer transceivers
- I/O port expansion
Procurement Notes
Verify RoHS compliance status as documentation indicates non-compliance. Confirm package type is 20-QSOP. Ensure supplier provides original Harris Corporation or authorized manufacturer documentation. Check for moisture sensitivity level requirements during storage and handling.
Selection Notes
Select this component for applications requiring octal buffering with three-state control. Compare propagation delay specifications against system timing requirements. Verify that the 20-QSOP package fits the PCB layout constraints. Ensure the supply voltage range matches the target circuit design.
Part Context
This part belongs to the Harris FCT (Fast CMOS) family, designed for high-speed digital applications. It serves as a direct replacement for similar octal buffers in legacy systems. The device integrates standard CMOS technology with improved switching speeds compared to older logic families.
Replacement Considerations
Check for pin-compatible alternatives such as the CY74FCT244CTQCT from Texas Instruments. Verify functional equivalence regarding output drive strength and propagation delay before substitution.
