CY74FCT652CTSOC

Overview

The CY74FCT652CTSOC 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 and features TTL-compatible input and output levels. The device provides three-state outputs with a low-level output current of 64 mA and a high-level output current of -32 mA. It exhibits a propagation delay of 5.7 ns and functions as a non-inverting logic circuit. The component is housed in a 24-pin SOIC package and supports surface mount installation.

Feature Summary

• Integrates eight-bit data storage capability alongside bidirectional bus transmission functionality.
• Provides controlled three-state output buffering for efficient system bus management.
• Ensures signal integrity through TTL-compatible voltage level interfacing.

Applications

• High-performance microprocessor-based systems requiring registered data latching
• Clocking data registers for synchronization in digital circuits
• Bus-oriented memory and I/O architectures

Procurement Notes

Verify the specific suffix 'CTSOCT' against official Texas Instruments documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity classification. Ensure compatibility with standard SOIC-24 footprints during PCB layout. Confirm RoHS compliance status via the manufacturer's latest environmental declaration before final procurement approval.

Selection Notes

Select this component when an application requires both bus driving and data registration in a single package. The FCT series offers CMOS performance with TTL compatibility, making it suitable for mixed-voltage environments. Consider the 5.7 ns propagation delay and 64 mA drive strength for timing-critical designs. Verify that the operating temperature range meets the specific environmental requirements of the target system.

Part Context

This part belongs to the CY74FCT652T series of registered bus transceivers. It is designed for high-speed digital applications where data integrity and precise timing are critical. The device serves as a key interface element between processors and peripheral devices, facilitating reliable data transfer across system buses while providing temporary storage for synchronized operations.

Replacement Considerations

Consult official substitution guides for equivalent registered bus transceivers. Verify pinout compatibility and electrical specifications such as drive current and propagation delay before replacing the component.
