Buffers, Drivers, Receivers, Transceivers FAQ

What is the function of the output enable pins?

The SN74HC541DW includes two output enable (OE) inputs that control the three-state outputs. When active low, the outputs are enabled; otherwise, they enter a high-impedance state.

Is the SN74HC541DW inverting or non-inverting?

The SN74HC541DW is a non-inverting buffer, meaning the output logic state follows the input logic state directly.
