CY74FCT244CTSOCT

Overview

The CY74FCT244CTSOCT is an octal buffer and line driver manufactured by Texas Instruments, belonging to the FCT logic series. It features eight non-inverting inputs with three-state outputs housed in a 20-pin SOIC package. The device operates on a single 5V supply ranging from 4.75V to 5.25V. Key electrical parameters include a propagation delay of 4.1ns at 5V, high-level output current of -32mA, and low-level output current of 64mA. Static current is specified at 200nA, with a maximum operating temperature of +85°C.

Feature Summary

• Provides octal buffering with three-state output capability for bus-oriented systems
• Features non-inverting logic function within the FCT CMOS technology family
• Designed for surface-mount installation in standard SOIC-20 packages

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffer circuits
• Bidirectional data bus transceivers

Procurement Notes

Verify the manufacturer designation carefully, as this component is produced by Texas Instruments despite the Cypress brand association in some listings. Confirm the specific suffix 'CTSOCT' matches the required tape-and-reel packaging format. Ensure the order reflects the correct voltage range and temperature specifications for your application environment.

Selection Notes

Select this component when an octal buffer with three-state control is required for 5V CMOS applications. It offers faster switching speeds compared to standard 74F series devices while maintaining lower power consumption. Consider the SOIC-20 footprint constraints and ensure compatibility with existing board layouts designed for this package type.

Part Context

This part belongs to the 74FCT (Fast CMOS) family, bridging the performance gap between TTL and CMOS technologies. It provides Schottky-like speed with CMOS power efficiency. The CY74FCT244 variant specifically focuses on unidirectional buffering, distinguishing it from bidirectional transceiver models like the 74FCT245.
