74FCT162244CTPAG8 Application Field and Working Principle

The 74FCT162244CTPAG8 is a high-speed CMOS device comprised of 48 non-inverting bidirectional buffers with 3-State outputs on 16 independent channels. It is ideal for applications requiring ultra-fast bus schedule times, withBus-Oriented Architecture. The 74FCT162244CTPAG8 has two separate two pipelines, with four sets of signal data that can be individually selected for transmission on four different signal lanes. Thus, it allows for a much faster system clock and data transfer requiring very low power consumption.

Features

• 48 non-inverting bidirectional buffers with 3-State outputs
• Ultra-fast bus schedule times, withBus-Oriented Architecture
• Independently selectable signal data on four different signal lanes
• Low power consumption

Application Field

The 74FCT162244CTPAG8 is especially suitable for applications such as:

• High-speed data transmission over small number of signal lanes, such as chip-to-chip communication
• Multi-chip module and multi-chip system designs
• High-performance embedded processors, system on-chip designs
• Low power backplanes
• Computer peripherals such as disk drives, network adapters, and modems
• High-speed memory interfaces
• High-performance video switches

Working Principle

The 74FCT162244CTPAG8 operates on the Data Bus Switching System (DBSS) principle, which allows for simultaneous transmission ofdata across four separate signal lanes and asynchronous transmission between them. The device consists of a group of high-speed input buffers, deskews and memory addresses, along with multiple sets of output buffers to receive data from each lane. The device has a built-in power saving feature that can enable/disable any number of channels as required, reducing system power consumption.

The device works by using an on-chip memory controller to manage each lane\'s read/write and data transfer operations. The controller\'s on-chip address decoder also provides for data packet arbitration between lanes, allowing for concurrent and synchronized transfers without need of an external controller. The device supports various data types and word lengths, making it a highly compatible device for various applications requiring high speed data transfers.

Conclusion

The 74FCT162244CTPAG8 is a fast CMOS device suitable for applications requiring ultra-fast bus schedule times and Bus-Oriented Architecture. It is ideal for applications such as high-speed data transmission over a small number of signal lanes, multi-chip module and multi-chip system designs, embedded processors and system on-chip designs. The device also features a low power backplane and can be used for high-performanceVideo Switching.
