74ACT240SJ

The 74ACT240SJ is a high-speed quad buffer, driver, receiver, and transceiver housed in a single unit. It is a dual-function device, meaning it performs two jobs in one package: it buffers data lines, and it also drives receivers. This dual function makes it ideal for use in high-performance, data-driven applications.The main features of the 74ACT240SJ include the following:• High performance: The 74ACT240SJ has high drive current, fast propagation delay, and low output impedances, enabling it to operate at high speeds.• Efficient power consumption: The 74ACT240SJ is designed to consume very little power, making it ideal for use in energy-conscious designs.• Versatility: The 74ACT240SJ is a dual-function device, meaning it can be used as either a buffer or a driver/receiver. This makes it suitable for a wide range of applications.• Reliability: The 74ACT240SJ is designed to operate reliably in a wide temperature range and a wide range of operating conditions.The 74ACT240SJ is commonly used in applications such as RAM and ROM memory, cache controllers, programmable logic devices, and addressable buses.

Application Fields

The 74ACT240SJ is ideally suited for data-driven applications where high speed, low power consumption, and reliability are paramount.The device is commonly used in memory and controller applications, such as in RAM and ROM memory, cache controllers, programmable logic devices, and addressable buses. It is also used in high speed data transfer systems, such as those found in industrial, medical, and commercial markets.

Working Principle

The 74ACT240SJ is a dual-function device, meaning it performs two jobs in one package: it buffers data lines, and it also drives receivers. The device is designed to operate in three basic modes. As a buffer, the 74ACT240SJ receives data on one input and passes it along to one output. As a driver, the device receives data on one input and drives it to two outputs. And as a receiver, the device receives data on two inputs and passes it along to one output.When used as a buffer, the 74ACT240SJ has a single input line and a single output line. In this mode, the input signal is first buffered before being passed along to the output line. This allows the output signal to be cleaner and less susceptible to noise and interference.When used as a driver, the 74ACT240SJ has a single input line and two output lines. The input signal is first buffered before being passed along to the two output lines. This allows for better synchronization with the data signals, allowing for higher performance and reliability.Finally, when used as a receiver, the 74ACT240SJ has two input lines and a single output line. The two input signals are synchronized and then combined before being passed along to the output line. This allows the device to recover data signals that may be subject to noise and interference.

Conclusion

The 74ACT240SJ is a high-performance, low-power, and reliable dual-function device. It is commonly used in RAM and ROM memory, cache controllers, programmable logic devices, and addressable buses. When operating in buffer mode, the 74ACT240SJ buffers the input signal before passing it along the output line. When operating in driver mode, the 74ACT240SJ drives the input signal to two output lines. And when operating in receiver mode, the 74ACT240SJ recovers data signals that may be subject to noise and interference.
