SN74AS646NT

The SN74AS646NT is a popular choice when it comes to Logic - Buffers, Drivers, Receivers, Transceivers. It is a low-voltage and low-power 8-bit buffer/driver circuit suitable for a wide range of applications, such as driving bus lines, port interface applications and more. In this article, we will discuss the SN74AS646NT application field and its working principle.

SN74AS646NT Application Field

The SN74AS646NT is suitable for a variety of applications, such as:

• Driving high capacitive bus lines, such as those found in telephone systems and communication networks.
• Interface high speed bus lines, such as those found in supercomputers.
• Drive port interface application (parallel ports, serial ports, USB).
• Driving large LCD display.

The SN74AS646NT is also suitable for use in systems that require low-voltage and low-power consumption, such as notebook computers and PDAs. The chip is also very resistant to noise and is capable of driving heavy loads.

SN74AS646NT Working Principle

The SN74AS646NT is a low-voltage 8-bit buffer/driver circuit. It is composed of 8 bidirectional buffer/drivers, which can be used either in unidirectional or bidirectional mode. Each buffer/driver is capable of driving an output of up to 20 mA, depending on the supply voltage.

The SN74AS646NT is controlled by three external signals: a chip enable (CE) signal, a mode enable (ME) signal, and an enable (E) signal. The CE signal sets the direction for all eight inputs, while the ME signal sets the direction for four pairs of buffering/drivers. The E signal disables all eight outputs.

The SN74AS646NT is powered by a low-voltage supply of between 2.7 V and 5.5 V. The chip is ESD-protected, so it can be safely used in environments where static electricity is present.

Conclusion

The SN74AS646NT is a popular choice for Logic - Buffers, Drivers, Receivers, Transceivers applications. The chip has multiple modes of operation and is capable of driving heavy loads. It is also very resistant to noise and is powered by a low-voltage supply. This makes the SN74AS646NT suitable for use in a wide range of applications.
