CY74FCT244TSOCT

Overview

The CY74FCT244TSOCT is an octal buffer and line driver manufactured by Texas Instruments, belonging to the FCT logic series. It features non-inverting CMOS logic with three-state outputs housed in a 20-SOIC 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 6.5 ns at 5 V, high-level output current of -32 mA, and low-level output current of 64 mA. Static current is specified at 200 nA, with a maximum operating temperature of +85°C.

Feature Summary

• Provides eight non-inverting buffer channels with tri-state output capability for bus driving applications.
• Utilizes advanced FCT CMOS technology to achieve high-speed signal transmission with low power consumption.
• Designed for surface-mount installation in compact electronic systems requiring reliable data buffering.

Applications

• High-speed data bus buffering in computer and industrial control systems
• Memory address and data bus drivers
• Clock distribution networks

Procurement Notes

Verify the specific suffix 'SOCT' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications and moisture sensitivity level. Ensure compatibility with existing PCB footprint dimensions for SOIC-20 packages. Cross-reference RoHS compliance status directly with the latest Texas Instruments documentation prior to procurement to meet environmental regulations.

Selection Notes

Select this component when designing circuits requiring octal buffering with high drive strength and fast switching speeds. The FCT series offers improved performance over standard 74F logic while maintaining pin compatibility. Consider the 20-SOIC package constraints and thermal dissipation requirements for the intended operating environment.

Part Context

This part belongs to the CY74FCT244T family of octal buffers. It serves as a digital logic interface component, distinct from transceivers like the CY74FCT245 or registered variants like the CY74FCT646. The device focuses on unidirectional signal amplification and isolation rather than bidirectional data transfer or storage functions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify functional equivalence with other octal FCT buffers if direct replacement is required.
