CY74FCT2244ATSOCT

Overview

The CY74FCT2244ATSOCT is an octal buffer and line driver manufactured by Texas Instruments, belonging to the FCT logic series. It features two non-inverting four-bit drivers with three-state outputs 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 -15 mA, and low-level output current of 12 mA. It supports surface mount installation and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Provides dual four-bit buffering with non-inverting logic for signal integrity
• Features three-state outputs to facilitate bus-oriented systems
• Designed for CMOS technology with TTL-compatible input levels

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffer circuits
• High-performance register files

Procurement Notes

Verify the specific suffix 'A' indicates the industrial temperature grade variant when sourcing. Confirm the 'TSOC' designation corresponds to the tube packaging format rather than tape and reel. Ensure the component matches the Texas Instruments manufacturing origin and RoHS compliance status required for the assembly process.

Selection Notes

Select this component for applications requiring octal buffering with controlled drive strength. The FCT series offers faster switching speeds compared to standard LS logic while maintaining CMOS power efficiency. Consider the 20-SOIC package dimensions for PCB layout constraints and thermal management requirements during design integration.

Part Context

This part is part of the CY74FCT2244T family, which includes variants with different packaging options such as TSSOP or SOIC. The base model defines the logical function, while suffixes denote temperature ranges and shipping formats. It serves as a critical interface component in digital systems requiring high-speed data transmission between buses and peripheral devices.

Replacement Considerations

Publicly confirmed substitute part numbers include 74FCT244ATSOG and 74FCT244CTSOG from Renesas Electronics Corporation. These alternatives offer similar functional characteristics and should be evaluated for pin compatibility and electrical parameter alignment before implementation.
