CY74FCT2245ATSOC

Overview

The CY74FCT2245ATSOC is an octal bus transceiver from the FCT logic series, manufactured by Texas Instruments. It features three-state outputs and operates within a supply voltage range of 4.75 V to 5.25 V. The device provides a propagation delay of 4.6 ns, with low-level output current capability of 12 mA and high-level output current of -15 mA. It supports TTL input and output levels and functions in non-inverting mode. Packaged in a 20-SOIC format, it is designed for surface mount installation and operates reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Octal configuration providing eight bidirectional data channels within a single integrated circuit package.
• Three-state outputs enable direct connection to system buses without additional pull-up or pull-down requirements.
• Non-inverting logic polarity ensures signal directionality remains consistent during transmission.

Applications

• High-speed data bus architectures requiring multiple parallel data paths
• Memory module interfacing where bidirectional data transfer is essential
• Industrial control systems utilizing standard TTL-compatible logic levels

Procurement Notes

Verify that the specific order suffix matches the required packaging type, as variations exist between tube and reel formats. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant aligns with the intended thermal management strategy for the target operating environment.

Selection Notes

Select this component when an octal width is required for efficient board space utilization compared to individual single-bit transceivers. The FCT series offers faster switching speeds than standard 74LS equivalents while maintaining compatible voltage thresholds. Evaluate the 20-SOIC package dimensions against available PCB footprint constraints before finalizing the design.

Part Context

This part belongs to the broader 74FCT family of high-speed CMOS logic devices. It serves as a specialized variant within the Texas Instruments portfolio, focusing on applications demanding rapid data throughput. The designation indicates its position as a standard transceiver solution for digital communication interfaces.

Replacement Considerations

CY74FCT2245ATSOCT is a documented equivalent offering identical electrical characteristics but supplied in tape-and-reel packaging instead of tubes.
