Working Principles

The SN74AS641DWRG4 is a buffer and line driver IC that amplifies and transmits digital signals. It features non-inverting operation, meaning the output signal is an exact replica of the input signal. The tri-state outputs allow the device to be connected to a common bus, enabling multiple devices to share the same communication lines.

When the output enable (OE) pin is high, the outputs are in the high-impedance state, effectively disconnecting them from the bus. This feature prevents conflicts when multiple devices attempt to drive the bus simultaneously.

The IC operates within a wide supply voltage range, making it suitable for various systems. It can drive capacitive loads due to its high output current capability.
