CY74FCT2652CTQCTG4

Overview

The CY74FCT2652CTQCTG4 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, non-inverting polarity, and a maximum propagation delay of 5.7 ns at 5 V with a 50 pF load. It supports low-level output currents up to 64 mA and high-level output currents up to -32 mA. The component is housed in a QSOP-24 package and functions as a registered transceiver suitable for surface-mount installation across an operating temperature range of -40 °C to +85 °C.

Feature Summary

• Integrates eight-bit data storage capability alongside bidirectional bus transmission functionality within a single integrated circuit.
• Provides controlled three-state output buffering to manage signal isolation on shared system buses effectively.
• Ensures compatibility with standard TTL logic families through defined input and output voltage threshold specifications.

Applications

• High-speed data routing between microprocessors and peripheral memory modules
• Bidirectional data buffering in industrial control systems requiring registered signal paths
• System interconnects in computing architectures utilizing FCT logic standards

Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance status against current manufacturer documentation. Confirm the QSOP-24 package dimensions match your PCB footprint requirements precisely. Check moisture sensitivity level ratings to ensure proper handling and reflow soldering profiles are followed during assembly processes.

Selection Notes

Select this component when an application requires simultaneous data latching and bidirectional transfer capabilities. The FCT series offers faster switching speeds compared to older 74LS equivalents while maintaining pin compatibility. Ensure the system power supply remains stable within the specified 4.75 V to 5.25 V window to maintain timing integrity.

Part Context

This part is part of the broader CY74FCT2652 family produced by Texas Instruments. It serves as a registered version of the standard bus transceiver, adding internal flip-flops to synchronize data movement. The G4 suffix typically denotes environmental compliance attributes such as lead-free composition, distinguishing it from standard commercial variants.

Replacement Considerations

Direct replacements include the CY74FCT2652CTQCT without the G4 suffix if lead content is not restricted. Other compatible options within the same family may include variations with different package types like SOIC-24, provided electrical characteristics remain identical.
