Working Principles

The 74ALVC16721MTDX operates as a buffer/line driver by receiving input data signals (D0-D15) and driving the corresponding output lines (Q0-Q15). The Output Enable (OE) inputs control the state of the outputs, allowing them to be either active or in a high-impedance state. When the OE input is low, the outputs are enabled and reflect the input data. Conversely, when the OE input is high, the outputs are disabled and enter a high-impedance state.
