The PI74FCT2828TQA is a high-speed CMOS bus interface register manufactured by Pericom (now Diodes Incorporated). It is part of the FCT (Fast CMOS Technology) family of logic devices, which are known for their high speed and low power consumption, making them suitable for a variety of digital systems where fast data transfer and low power dissipation are critical.

Applications

• Memory interface: Used in memory systems as a buffer or register to improve data transfer speeds.
• Bus buffering: Employed as a bus buffer in computer systems and other digital devices to isolate and protect buses.
• Data acquisition systems: Found in data acquisition systems for temporary storage of data during processing.
• Networking equipment: Utilized in networking devices as a register or buffer for data packets.

Features

• High speed: Provides fast data transfer rates due to its FCT technology.
• Low power consumption: Consumes minimal power, making it suitable for battery-powered and energy-efficient systems.
• TTL compatible inputs: Compatible with TTL (Transistor-Transistor Logic) signal levels.
• 3-state outputs: Features 3-state outputs that allow for bus isolation.

Benefits

• Improved system performance: Enables faster data transfer and processing, leading to improved system performance.
• Reduced power consumption: Minimizes energy consumption in power-sensitive applications.
• Simplified system design: TTL compatible inputs simplify interfacing with other logic devices.
• Enhanced bus protection: 3-state outputs provide bus isolation, protecting the bus from signal contention and damage.

Additional Details

The PI74FCT2828TQA is typically an 8-bit register with specific propagation delay characteristics. The specific voltage and current ratings, as well as the operating temperature range, are detailed in the datasheet. Package types vary depending on the manufacturer. It's often used where buffering and direction control are required on data buses.

When implementing the PI74FCT2828TQA, proper power supply decoupling is important to minimize noise and ensure stable operation. Terminating resistors may also be required on the bus lines to prevent signal reflections and ensure signal integrity.
