Overview
The 74AHCT125D,118 is a quad buffer/line driver with 3-state outputs, manufactured by Nexperia USA Inc. This integrated circuit is part of the 74AHCT series, which is designed for operation in a wide range of applications requiring low power consumption and high noise immunity. The device features four independent buffer gates, each with a separate output enable input that can place the corresponding output in a high impedance state when driven high. This makes it versatile for use in mixed voltage environments and as a translator between different logic levels.
