CY74FCT244DTSOCTE4

Overview

The CY74FCT244DTSOCTE4 is an octal buffer and line driver manufactured by Texas Instruments. It features eight non-inverting buffers with three-state outputs, designed for high-speed signal buffering and driving applications. The device operates within a supply voltage range of 4.75 V to 5.25 V and utilizes CMOS logic technology. It is housed in a 20-pin SOIC package suitable for surface mount installation. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides eight independent non-inverting buffer channels for signal conditioning
• Features three-state outputs to facilitate bus-oriented architectures
• Utilizes Fast CMOS (FCT) technology for high-speed performance

Applications

• High-speed data buffering in digital systems
• Bus driver applications requiring controlled impedance
• Signal isolation between different circuit sections

Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance when sourcing. Confirm the 'DT' designation corresponds to the correct SOIC package width and thermal characteristics. Ensure the manufacturer is identified as Texas Instruments or its authorized successor entity for Cypress products. Cross-reference the full part number against official distributor catalogs to confirm current production status and availability.

Selection Notes

Select this component when an octal buffer with three-state capability is required for 5V logic systems. It is suitable for designs needing high drive strength and low propagation delay. Consider the SOIC-20 package constraints for PCB layout. Verify that the input voltage levels are compatible with the system's logic family before integration.

Part Context

This part belongs to the CY74FCT244 series of octal buffers and line drivers. It is part of the broader FCT logic family, which bridges the performance gap between standard TTL and advanced CMOS technologies. The device is commonly used in memory and microcontroller-based systems where signal integrity and speed are critical.

Replacement Considerations

Check for CY74FCT244 variants with different suffixes for package or temperature changes. Other manufacturers may offer pin-compatible alternatives within the same FCT logic family. Verify electrical specifications match exactly before substitution.
