Overview
The 74AHC126PW/C1118 is a quad buffer/line driver produced by NXP USA Inc. This component is part of the AHC (Advanced High-speed CMOS) family and is designed to provide high-speed buffering and line driving capabilities. It features 3-state outputs controlled by the output enable inputs (nOE), allowing the outputs to assume a high-impedance OFF-state when nOE is LOW. This makes it suitable for use in mixed voltage environments and as translators between different logic levels.
