CY74FCT2245TSOC

Overview

The CY74FCT2245TSOC is an octal bus transceiver from the FCT logic series, manufactured by Texas Instruments. It features tri-state outputs and operates within a supply voltage range of 4.75 V to 5.25 V. The device supports TTL input and output levels with a propagation delay of 7 ns. It provides a low-level output current of 12 mA and a high-level output current of -15 mA. Packaged in a 20-pin SOIC format, it functions as a non-inverting standard transceiver suitable for surface mount applications across a temperature range of -40°C to +85°C.

Feature Summary

• Octal bidirectional data transfer capability with tri-state control
• TTL-compatible input and output voltage levels
• Integrated series damping resistors for signal integrity

Applications

• High-speed data bus architectures
• Memory-to-memory or memory-to-I/O transfers
• Bus-oriented communication systems

Procurement Notes

Verify the specific suffix 'TSOC' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with system voltage requirements of 4.75 V to 5.25 V. Confirm that the 7 ns propagation delay meets timing constraints. Check RoHS compliance status via the official product page before procurement.

Selection Notes

Select this component when an octal bus transceiver with integrated damping resistors is required for noise reduction. Compare performance metrics such as the 7 ns delay and 12/15 mA drive currents against alternative FCT series devices. Ensure the SOIC-20 package fits the PCB layout constraints. Verify that the TTL level compatibility matches the source and destination logic families in the design.

Part Context

This part belongs to the CY74FCT2245T family of octal bus transceivers. It shares functional similarities with other FCT series devices but includes unique series damping resistors. The TSOC suffix indicates a specific tape-and-reel packaging variant within the broader SOIC-20 product line offered by Texas Instruments for automated assembly processes.

Replacement Considerations

CY74FCT2245ATSOCT is a verified substitute offering identical functionality in the same package.
