Working Principles

The SN74HC244PWR operates by receiving input signals on its input pins (IO1 to IO16) and amplifying them to provide corresponding output signals. The Output Enable (OE) pins control the activation of the outputs. When OE is low, the outputs are enabled, allowing the amplified signals to pass through. Conversely, when OE is high, the outputs are disabled, resulting in a high-impedance state.
