CY74FCT2652CTQC

Overview

The CY74FCT2652CTQC is an octal bus transceiver and register manufactured by Cypress Semiconductor Corp, belonging to the FCT logic series. It features eight non-inverting channels with three-state outputs, designed for high-speed data transmission. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL input and output levels. Key electrical characteristics 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 reliably across an operating temperature range from -40°C to +85°C and is housed in a QSOP-24 package.

Feature Summary

• Integrates registered bus transceiver functionality with octal data paths
• Provides three-state outputs for efficient bus line management
• Supports non-inverting signal transmission with TTL-compatible levels

Applications

• High-speed data bus systems requiring registered buffering
• Memory-to-memory or memory-to-I/O data transfers
• Clock domain crossing applications in digital circuits

Procurement Notes

Verify the manufacturer designation as Cypress Semiconductor Corp against the specific datasheet documentation. Confirm the package type matches the QSOP-24 specification and ensure the operating temperature range aligns with system requirements. Cross-reference the part number suffixes to confirm exact electrical and mechanical tolerances before procurement.

Selection Notes

Select this component when an octal registered transceiver with three-state outputs is required for high-speed digital interfaces. Ensure the design accommodates the specified 5.7 ns propagation delay and the 4.75 V to 5.25 V power supply constraints. Verify that the QSOP-24 footprint fits the PCB layout and that thermal management supports the -40°C to +85°C operational range.

Part Context

This component belongs to the FCT (Fast CMOS) logic family, which bridges the performance gap between standard CMOS and ECL technologies. The CY74FCT2652 variant specifically adds registration capabilities to the standard bus transceiver function, allowing data latching at the receiver end. This integration reduces external component count and improves timing control in complex digital systems.
