CY74FCT16245ETPVCT

Overview

The CY74FCT16245ETPVCT is a 16-bit bus transceiver manufactured by Cypress Semiconductor. It features three-state outputs and operates with a single power supply ranging from 4.5V to 5.5V. The device supports data transfer in both directions between two buses, controlled by a direction control input. It includes an output enable input that allows the outputs to be disabled independently of the direction control. The component is designed for high-speed applications, offering low propagation delays and reduced power consumption compared to earlier logic families.

Feature Summary

• Provides 16-bit bidirectional data transfer capability between two separate buses
• Features three-state outputs that can be enabled or disabled via control inputs
• Operates on a single 5V power supply with defined voltage ranges
• Designed for high-speed performance with low propagation delay characteristics

Applications

• High-speed data bus interfaces in computer systems
• Memory-to-memory data transfers
• Bus-oriented communication links
• Data acquisition systems requiring bidirectional signal routing

Procurement Notes

Verify the specific suffix 'CT' indicates tape and reel packaging when ordering. Confirm the temperature range matches application requirements, as industrial variants may differ. Ensure compatibility with system voltage levels before integration. Check for obsolescence status through official Cypress or Infineon channels, as product lifecycles change. Validate pinout compatibility if replacing existing designs.

Selection Notes

Select this component when 16-bit bidirectional buffering is required with single-supply operation. Consider the FCT family for faster switching speeds compared to standard FCT devices. Evaluate package constraints, as the TQFP-48 form factor suits surface-mount applications. Verify noise immunity needs, as FCT devices offer improved noise margins over older technologies.

Part Context

This part belongs to the CY74FCT series of fast CMOS logic devices produced by Cypress Semiconductor, now part of Infineon Technologies. The FCT designation signifies Fast CMOS technology, optimized for speed and power efficiency. The 16245 variant specifically denotes a 16-bit bus transceiver configuration within this logical family.

Replacement Considerations

Direct replacements include other 16-bit bus transceivers from the same FCT family, such as the CY74FCT16245ETP. Cross-reference with equivalent parts from other manufacturers like Texas Instruments or NXP, ensuring identical pinouts and electrical specifications are maintained for seamless integration.
