Overview
The 74AHCT125D-Q100,11 is a quad buffer/line driver with 3-state outputs, manufactured by Nexperia USA Inc. This integrated circuit is part of the 74AHCT family and is designed to operate in a wide range of applications, particularly in mixed voltage environments. The device features output enable inputs (nOE) that control the 3-state outputs, allowing the outputs to assume a high impedance OFF-state when nOE is HIGH. This makes it suitable for use as a translator in various electronic systems.
