The IDT74FCT399P is a Quad 2-Input Multiplexer with D-Type Storage manufactured by Renesas Electronics America. It is part of the FCT (Fast CMOS Technology) family, designed for high-speed performance with low power consumption. This device combines multiplexing and storage capabilities, making it suitable for applications where data selection and temporary storage are needed.

Applications:

• Data selection
• Address multiplexing
• Data storage
• High-speed computing
• Digital systems

Features:

• Quad 2-input multiplexer: Selects one of two inputs for each of the four channels.
• D-type storage: Provides temporary storage for the selected data.
• Fast CMOS Technology (FCT): Enables high-speed operation and low power consumption.
• TTL-compatible inputs: Allows easy interfacing with TTL logic levels.
• Three-state outputs: Permits bus isolation and expansion.
• Common select input: Controls the selection of inputs for all four multiplexers simultaneously.

Benefits:

• Increased system speed: High-speed operation enhances overall system performance.
• Reduced power consumption: FCT technology minimizes power dissipation, suitable for energy-efficient applications.
• Simplified interfacing: TTL-compatible inputs facilitate integration with other logic devices.
• Enhanced data handling: Multiplexing and storage capabilities provide flexible data handling options.
• Flexible system design: Three-state outputs allow for versatile system configurations.

Additional Details:

The IDT74FCT399P operates from a 5V power supply and is available in a DIP (Dual In-line Package). Its combination of multiplexing and storage in a single device reduces component count and simplifies circuit design. The common select input makes it easy to control all four multiplexers at once. The three-state outputs allow multiple devices to share a common bus. The IDT74FCT399P is a reliable and efficient solution for applications requiring data selection and storage.
