Working Principles
SN74ALS244C-1DW operates by receiving digital input signals on its input pins (A1-A8) and amplifying/buffering them to produce corresponding output signals on the output pins (Y1-Y8). The Output Enable (OE) pin controls the activation of the outputs. When OE is low, the outputs are enabled, allowing the amplified/buffered signals to propagate through. Conversely, when OE is high, the outputs are disabled, effectively isolating them from the input signals.
