The CY74FCT244DTSOCTE4 is a high-speed CMOS octal buffer/line driver designed for asynchronous communication between wide data and address buses. The device is designed for two-way communications allowing data flow in both directions. It provides eight non-inverting buffers with 24mA sink/source capability. The CY74FCT244DTSOCTE4 is fabricated with advanced CMOS logic, with an output voltage range that is compatible with both TTL and CMOS logic levels. All outputs have totem pole structure, which results in improved output drive, confirmed to increase dynamic bus bandwidth.

The CY74FCT244DTSOCTE4 becomes an efficient line driver, due to its capability to increase and decrease the logic level of a data line. The device has the additional feature of energy savings due to its low power consumption. All these features make it suitable for applications where maximum performance and minimum power consumption are desired. It is designed for asynchronous communication between data buses, and is ideal for a variety of applications including Personal Computers (PCs), printers, keyboards, modems and motherboards.

The CY74FCT244DTSOCTE4 has an active-low output enable (OE) input to control the output state of the device. It is accomplished by the presence of a low-level current which suffices to supply the entire logic family. The outputs can be configured in an active-low state or an active-high state by an active-low output enable input. This feature makes it compatible for use in different kinds of logic systems.

The CY74FCT244DTSOCTE4 can be used as a bus transceiver, allowing bi-directional communication between two buses. The device is easy to configure, as the data direction can be easily determined by a single pin without the need for complex configuration or programming. When OE is low, the data is transmitted from the A inputs to the B outputs. If OE is high, data are transmitted from the B inputs to the A outputs.

The CY74FCT244DTSOCTE4 has high-speed operation, making it an ideal choice for driving high-speed buses. It operates at frequencies of up to 100MHz and has a propagation delay time of 24ns (pulse test). The device offers improved thermal performance and higher switching speed compared to other similar devices. This improves overall system performance and makes it more energy efficient.

The CY74FCT244DTSOCTE4 provides several other features, making it an attractive choice for a variety of applications. The device has an open-drain output, meaning it can be used as an open collector or bus transceiver without additional components. It also has an inrush current limiter to protect downstream components from high inrush current during switching. The output also has built-in diode protection, allowing it to be interfaced to most logic families.

In summary, the CY74FCT244DTSOCTE4 is a high-speed CMOS octal buffer/line driver designed for asynchronous communication between wide data and address buses. It provides high-speed operation, low power consumption, improved thermal performance, organized packaging, and open-drain outputs. It is suitable for various applications, including PCs, printers, modems and motherboards. All these features make the CY74FCT244DTSOCTE4 an efficient and attractive solution for logic-level conversion, and make it suitable for use in logic systems of all types.
