Overview
The 74LVC2G126DC-Q100 is a dual buffer/line driver with 3-state outputs, designed and manufactured by Nexperia USA Inc. This device is part of the LVC (Low Voltage CMOS) family and is optimized for operation in a wide range of supply voltages from 1.65 V to 5.5 V. It features output enable inputs (nOE) that control the 3-state outputs, making it suitable for use in mixed 3.3 V and 5 V environments as a translator. The device is fully specified for partial power-down applications using IOFF circuitry, which prevents damaging backflow current when the device is powered down.
