Working Principles

The 74ABT240DB,118 operates by receiving input signals on its eight input channels (A1-A8) and providing buffered output signals on the corresponding output channels (Y1-Y8). The direction of signal flow is controlled by the Output Enable (OE#) pin. When OE# is low, the device is enabled, and the input signals are transmitted to the output channels. Conversely, when OE# is high, the outputs are in a high-impedance state, effectively disconnecting them from the input channels.
