Working Principles

SN74BCT244NSR operates by receiving input signals on its designated pins (A1-A8) and amplifying them using internal circuitry. The amplified signals are then transmitted to the corresponding output pins (Y1-Y8). The output enable pin (OE) controls the activation of the outputs. When OE is low, the outputs are enabled, and when OE is high, the outputs are in a high-impedance state.
