Working Principles

The 74AHCT541PW,118 operates by receiving digital input signals on its data inputs (I/O1 to I/O7) and buffering/amplifying them to the corresponding outputs. The OE# (Output Enable) pin controls the output state, allowing the IC to be enabled or disabled as needed. When enabled, the IC actively drives the outputs based on the input signals. When disabled, the outputs are in a high-impedance state, effectively disconnecting them from the circuit.
