CY74FCT652ATSOC

Overview

The CY74FCT652ATSOC is an octal bus transceiver and register manufactured by Texas Instruments. It belongs to the FCT logic series and features three-state outputs. The device operates within a supply voltage range of 4.75 V to 5.25 V. It exhibits a propagation delay of 6.3 ns. The low-level output current is 64 mA, while the high-level output current is -32 mA. Input and output levels are compatible with TTL standards. The component functions in temperatures from -40°C to +85°C and is housed in a SOIC-24 package.

Feature Summary

• Integrates eight bidirectional data paths with registered storage capability for synchronized data transfer.
• Provides three-state outputs to facilitate direct connection to system buses without additional drivers.
• Ensures TTL-compatible input and output voltage levels for broad interface interoperability.

Applications

• High-speed data acquisition systems requiring buffered and registered signal paths
• Memory mapping circuits utilizing octal bus architectures
• Industrial control interfaces managing multiple peripheral devices

Procurement Notes

Verify the specific suffix ATSOC against official Texas Instruments documentation to confirm the SOIC-24 package type and industrial temperature rating. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement decisions.

Selection Notes

Select this component when an octal configuration with internal registration is required for bus isolation. The FCT technology offers faster switching speeds compared to standard CMOS alternatives. Verify that the 64 mA drive strength meets the load requirements of the connected bus lines.

Part Context

This part is a member of the Texas Instruments 74FCT family, designed for high-performance digital applications. It serves as a registered transceiver, combining buffering with data latching functionality. The FCT series utilizes Fast CMOS technology to achieve performance levels comparable to transistor-transistor logic while maintaining CMOS power efficiency.

Replacement Considerations

The CY74FCT652CTSOCTG4 is a verified equivalent offering identical electrical characteristics and pinout compatibility. Both parts function as octal bus transceivers with registers and share the same SOIC-24 packaging format.
