CY74FCT2652CTQCT

Overview

The CY74FCT2652CTQCT is an octal bus transceiver with register functionality manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and features three-state outputs. The device utilizes the FCT logic series and supports TTL input and output levels. It is housed in a QSOP-24 package and offers a propagation delay of 5.7 ns. The component provides 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 suitable for high-speed data transfer applications.

Feature Summary

• Integrates eight-bit registration capability with bus transceiver functionality for synchronized data handling
• Provides three-state outputs to facilitate efficient bus line management and isolation
• Supports TTL-compatible input and output voltage levels for broad system integration

Applications

• High-speed data bus architectures requiring registered buffering
• Memory interface circuits needing synchronized data latching
• I/O port expansion systems utilizing bus transceivers

Procurement Notes

Verify the specific suffix 'CTQCT' against the manufacturer's latest datasheet to confirm package type and moisture sensitivity classification. Ensure compatibility with existing PCB footprint requirements for the QSOP-24 package. Confirm that the operating temperature range meets the environmental specifications of the target application before finalizing procurement decisions.

Selection Notes

Select this component when an octal bus transceiver with integrated storage is required for synchronous data paths. The FCT series offers faster switching speeds compared to standard LS logic. Consider the 5.25 V maximum supply voltage constraint and ensure the system design accommodates the specified TTL input thresholds for reliable signal interpretation across the operating temperature range.

Part Context

This part belongs to the CY74FCT family of fast CMOS logic devices produced by Texas Instruments. The FCT series is designed to provide performance comparable to Schottky TTL while maintaining CMOS power consumption benefits. The 2652 variant specifically combines transceiver and register functions, distinguishing it from simple buffer or driver components within the same logical product line.
