Working Principles

The 74FCT3244ASOG operates by receiving input signals through its input pins (A1-A4, B1-B4) and buffering them to the corresponding output pins (Y1-Y5). The output enable pins (OE1-OE4) control the activation or deactivation of the buffer outputs. When the OE pin is low, the outputs are enabled, allowing data transmission. Conversely, when the OE pin is high, the outputs are disabled, effectively isolating the inputs from the outputs.
