CY74FCT652ATQCT

Overview

The CY74FCT652ATQCT is an octal bus transceiver and register with three-state outputs, manufactured by Texas Instruments. It belongs to the FCT logic series and operates within a supply voltage range of 4.75 V to 5.25 V. The device features TTL-compatible input and output levels, ensuring compatibility with standard digital systems. It exhibits a propagation delay of 6.3 ns and supports low-level output currents up to 64 mA and high-level output currents of -32 mA. Designed for surface-mount applications, it is housed in a QSOP-24 package and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates bus transceiver functionality with internal data latching capabilities for synchronized signal handling.
• Provides three-state outputs to facilitate efficient bus line management and system isolation.
• Ensures signal integrity through TTL-compatible input and output voltage thresholds.

Applications

• High-speed data buffering in computer architectures
• Clock drivers and timing synchronization circuits
• Control signal routing in industrial automation systems

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official Texas Instruments documentation. Confirm that the specific suffix matches the required QSOP-24 package configuration. Ensure compliance with RoHS directives and check moisture sensitivity levels prior to soldering. Validate that the received units match the specified electrical parameters and packaging format.

Selection Notes

Select this component when an octal bidirectional interface with data storage is required. It is suitable for designs needing fast switching speeds and robust drive capability. Consider the QSOP-24 footprint constraints during PCB layout. Verify that the system voltage aligns with the 5V nominal requirement and that thermal conditions remain within the specified operational limits.

Part Context

This device is part of the Texas Instruments 74FCT family, which combines CMOS density with TTL speed. The CY74FCT652 specifically addresses applications requiring both data transmission and temporary storage. It serves as a critical interface element between microprocessors and peripheral memory or I/O devices in complex electronic assemblies.

Replacement Considerations

Consult official substitution guides for compatible alternatives such as the CY74FCT652TQCT. Verify pinout compatibility and electrical specifications before implementation. Ensure any substitute maintains the same package type and functional characteristics.
