Working Principles

The IDT74LVC244AQ8 operates by receiving input signals on the A1-A8 pins and transmitting the corresponding buffered output signals on the Y1-Y8 pins. The direction of data flow is controlled by the OE (Output Enable) pin. When OE is low, the outputs are enabled, allowing data transmission. Conversely, when OE is high, the outputs are disabled, effectively isolating the input from the output.
