CY74FCT2652ATQCT

Overview

The CY74FCT2652ATQCT is an octal bus transceiver and register with 3-state outputs manufactured by Texas Instruments. It belongs to the FCT logic series and features non-inverting polarity. The device operates within a supply voltage range of 4.75 V to 5.25 V, supporting TTL input and output levels. It provides a low-level output current of 64 mA and a high-level output current of -32 mA. The propagation delay is specified at 6.3 ns. Designed for surface-mount installation, it is housed in a QSOP-24 package. The component functions reliably across an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Integrates eight-bit registered bus transceiver functionality with three-state outputs for efficient data buffering and direction control.
• Supports TTL-compatible input and output voltage levels for seamless interface with standard digital logic systems.
• Delivers high drive capability with significant low-level and high-level output currents to maintain signal integrity.

Applications

• High-speed data bus architectures requiring registered buffering
• Memory-to-peripheral interface circuits
• System-level data routing and direction control

Procurement Notes

Verify the specific package variant, as the model suffix indicates a QSOP-24 form factor. Confirm moisture sensitivity handling requirements during storage and assembly. Ensure the design accommodates the specified 4.75 V to 5.25 V power supply constraints. Validate thermal management for the -40 °C to +85 °C operational range. Cross-reference the datasheet for exact pinout configurations to prevent PCB layout errors.

Selection Notes

Select this component when an octal registered transceiver with three-state outputs is required for bus applications. It is suitable for designs needing TTL level compatibility and moderate propagation delays around 6.3 ns. Consider the QSOP-24 package constraints for board space. Evaluate the 64 mA low-level output current against load requirements. Compare against similar FCT series devices if different packaging or speed characteristics are needed.

Part Context

This part is part of the CY74FCT2652T family of registered bus transceivers. It shares functional similarities with other FCT series components but offers specific integration of registration and bidirectional transfer. The device addresses needs for synchronized data latching on buses. It complements unregistered transceivers by providing state retention capabilities essential for complex digital systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with direct replacements by matching the FCT logic family, QSOP-24 package, and electrical specifications such as voltage range and output current capabilities.
