Working Principles

The CD74HC541PWRE4 is an octal buffer/line driver that operates using CMOS technology. It takes input signals from the A1-A8 pins and amplifies them to drive corresponding output signals on the Y1-Y8 pins. The OE (Output Enable) pin controls the 3-state outputs, allowing the device to be enabled or disabled as needed. When the OE pin is high, the outputs are active; when it is low, the outputs are in a high-impedance state.
