Working Principles

The 74LVC240AD,118 is based on CMOS technology, which allows for low-power operation and high noise immunity. It functions as an octal inverting buffer/line driver, meaning that it can invert the logic level of its input signals and drive the output lines accordingly. The 3-state outputs provide flexibility by allowing the outputs to be disabled, effectively disconnecting them from the rest of the circuit.
