Overview
The 74AHCT125D,112 is a quad buffer/line driver with 3-state outputs, produced by Nexperia (formerly part of NXP Semiconductors). This device is designed for high-speed applications and is pin compatible with low power Schottky TTL (LSTTL). It features four independent buffers, each with a 3-state output controlled by the output enable input (nOE). This allows the outputs to assume a high impedance OFF-state when nOE is HIGH, making it suitable for use in mixed voltage environments as a translator.
