Overview
The SN74LS541NSR is an octal buffer and line driver produced by Texas Instruments. This component is part of the 74LS series and is designed to provide high-performance buffering and line driving capabilities. It features a unique pinout where all inputs are on one side of the package and all outputs are on the opposite side, enhancing printed circuit board layout efficiency. The SN74LS541NSR offers true data at the outputs and includes 3-state outputs, which can be controlled by a 2-input NOR gate.
