Overview
The 74LVC2G125DC-Q100 is a dual bus buffer/line driver with 3-state outputs, designed and manufactured by Nexperia (previously part of NXP USA Inc.). This device is particularly useful in mixed 3.3 V and 5 V environments due to its ability to translate signals between these voltage levels. It features Schmitt-trigger action at all inputs, enhancing noise immunity and tolerance to slower input rise and fall times. The device is fully specified for partial power-down applications using IOFF circuitry, which prevents backflow current when the device is powered down.
