Application Field

The PI74LPT244QE is suitable for data interface and bus switching applications, such as general purpose switching of digital and analog signals, interfacing with bus-oriented interface applications, and bus expansion applications. It can also be used for microcontroller data communications, such as UART and serial data busses.

It is ideal for digital data transmission applications in which high speed, low power, and improved signal integrity are required, such as cell phones, PDAs, digital video, automotive applications, and TVs. Additionally, the PI74LPT244QE can be used in the industrial and home automation industries.

Working Principle

The PI74LPT244QE works by receiving data on its input pins, and transferring it to the output pins. It uses an input buffer to receive data, and an output buffer to transfer data. The buffer can be configured to support various data formats, such as 8 or 16 bit parallel or serial data. The output buffer is capable of driving up to 8 loads, providing improved data transfer and signal integrity. The output buffer also has an enable pin, allowing the user to selectively enable or disable the IC.

The low power operation of the PI74LPT244QE is achieved by reducing the power drawn by the input and output buffer. The input buffer can be configured to operate at either 1.275 volts or 1.8 volts, reducing power consumption significantly. The output buffer can be configured to either on or off, which further reduces power consumption. Additionally, the data rate of the PI74LPT244QE can be adjusted, allowing the device to be configured to only transmit data when required. This further reduces power consumption.

The PI74LPT244QE is also designed to provide improved signal integrity. It has built-in ESD protection for its inputs and outputs, ensuring that data is transferred accurately and reliably. Additionally, it has a wide operating temperature range of -40°C to +125°C, making it suitable for a range of applications and environments.

Conclusion

The PI74LPT244QE is an active, low power, 3-state, 5-port buffer IC, suitable for various data interface, bus switching, and bus expansion applications. It offers improved impedance matching using its integrated buffer technology, as well as excellent AC performance and improved signal integrity. With its wide variety of applications, superior performance, and low power operation, the PI74LPT244QE is an ideal solution for a range of applications.
