CY74FCT652CTSOCG4

Overview

The CY74FCT652CTSOCG4 is an octal bus transceiver and register manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V. The device features TTL-compatible input and output levels with three-state outputs. Key electrical parameters include a propagation delay of 5.7 ns, a low-level output current of 64 mA, and a high-level output current of -32 mA. It functions as a non-inverting registered transceiver in an SOIC-24 package.

Feature Summary

• Integrates eight D-type flip-flops with three-state bus transceiver functionality for simultaneous data storage and transmission.
• Provides TTL-compatible logic levels for inputs and outputs to ensure compatibility with standard digital interfaces.
• Features independent control mechanisms for direction and output enablement to manage bidirectional data flow.

Applications

• High-performance microprocessor-based systems requiring registered bus interfacing
• Memory mapping circuits utilizing octal data latching
• Industrial control systems needing reliable bidirectional data transfer

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence when sourcing. Confirm the SOIC-24 package dimensions match your PCB footprint requirements. Ensure the operating temperature range of -40°C to +85°C aligns with your environmental specifications. Cross-reference the manufacturer part number directly with official Texas Instruments documentation to avoid counterfeit components.

Selection Notes

Select this component when both data registration and bidirectional bus driving are required in a single package. The FCT logic series offers faster switching speeds compared to standard LS or ALS families. Consider the 64 mA sink capability for driving moderate capacitive loads on the bus lines without external buffering.

Part Context

This part belongs to the CY74FCT652T family of registered bus transceivers. It serves as a bridge between processors and peripheral devices, combining the functions of a latch and a driver. The G4 suffix typically denotes environmental compliance modifications within the same functional specification.

Replacement Considerations

CY74FCT652CTSOCT is a compatible variant within the same family offering identical electrical characteristics and pinout configuration.
