CY74FCT245TSOC

Overview

The CY74FCT245TSOC 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 supports TTL input and output levels with a propagation delay of 7 ns. It provides a low-level output current of 64 mA and a high-level output current of -32 mA. Packaged in a 20-SOIC format, it functions as a non-inverting transceiver suitable for surface mount applications across a temperature range of -40°C to +85°C.

Feature Summary

• Octal bidirectional data transfer capability with common control direction pins
• Three-state outputs designed to minimize power consumption during idle states
• TTL-compatible input and output voltage levels for direct interface with standard logic

Applications

• High-speed data bus architectures requiring eight-bit parallel transmission
• Memory-to-memory or memory-to-I/O data transfers in computing systems
• Buffering and driving of external buses in industrial control environments

Procurement Notes

Verify the specific suffix against the manufacturer's latest datasheet to confirm package dimensions and pinout compatibility. Ensure the ordering code matches the required tape-and-reel or tube packaging configuration. Cross-reference the RoHS status and material set change notices (PCN) to guarantee compliance with current environmental regulations and manufacturing standards before finalizing procurement orders.

Selection Notes

Select this component when an octal, non-inverting bus transceiver with FCT speed characteristics is required. It is appropriate for designs needing 7 ns propagation delay and strong drive capabilities at 5V logic levels. Consider the 20-SOIC package constraints for PCB layout. Verify that the system operating temperature falls within the specified commercial/industrial range and that supply voltages remain strictly between 4.75 V and 5.25 V.

Part Context

This part belongs to the CY74FCT245T family of octal bus transceivers. It serves as a standard interface solution for connecting microprocessors, memory devices, and peripheral chips. The FCT series is characterized by CMOS construction with TTL-compatible inputs, offering faster switching speeds than legacy 74LS families while maintaining lower power consumption. The TSOC designation specifically identifies the SOIC-20 surface-mount package variant.

Replacement Considerations

CY74FCT245ATSOCT is a verified substitute part number within the same product family, offering identical functional specifications but supplied in tape-and-reel packaging instead of tubes.
