Working Principles

The SN74AHCT240PWG4 is an octal buffer/line driver IC that operates as a non-inverting buffer. It takes input signals from the A1 to A7 pins and provides corresponding output signals on the Y1 to Y8 pins. The OE (Output Enable) pin controls the output state, allowing the user to enable or disable the outputs.

When the OE pin is low, the outputs are active and mirror the input signals. Conversely, when the OE pin is high, the outputs are in a high-impedance state, effectively disconnecting them from the circuit.
