CY74FCT245DTQC

Overview

The CY74FCT245DTQC is an octal bus transceiver from the FCT logic series, manufactured by Texas Instruments. It features eight bidirectional data channels with three-state outputs and operates within a supply voltage range of 4.75 V to 5.25 V. The device utilizes TTL-compatible input and output levels. It is housed in a 20-pin SSOP package designed for surface-mount installation. The component supports an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Provides bidirectional data transmission across eight independent channels
• Features three-state outputs to facilitate direct system bus interconnection
• Ensures compatibility with TTL logic input and output voltage levels

Applications

• Memory mapping applications requiring high-speed data transfer
• Clock drivers for synchronous bus architectures
• Bus-oriented communications between microprocessors and peripheral devices

Procurement Notes

Verify the specific suffix DTQC against official Texas Instruments documentation to confirm the exact package type and environmental compliance status. Ensure the ordering information matches the required pin configuration and thermal characteristics for your design. Cross-reference the manufacturer's latest datasheet to validate current production status and any potential material set changes or PCN notifications affecting this specific part number.

Selection Notes

Select this component when designing systems that require robust bidirectional data flow with minimal loading effects. The FCT technology offers faster switching speeds compared to standard CMOS counterparts while maintaining TTL compatibility. Consider the SSOP package constraints regarding board space and thermal dissipation. Verify that the load capacitance requirements align with the propagation delay specifications provided in the official electrical characteristics table.

Part Context

This device belongs to the CY74FCT245T family of octal bus transceivers. It shares functional similarities with other members like the CY74FCT245TSOC but differs in physical packaging. The FCT series is engineered for high-performance digital applications, bridging the gap between speed and power consumption. It serves as a critical interface element in complex digital logic designs requiring reliable data direction control.

Replacement Considerations

Direct substitutes include CY74FCT245ATQC and CY74FCT245DTQCTE4. Verify pinout compatibility and electrical parameters before substitution.
