Quad 2-input NOR gate
BU4001B / BU4001BF
The BU4001B and BU4001BF are 2-input positive logic NOR gates, each with four built-in circuits. A buffer achieved by an inverter added at the gate output improves the input / output propagation characteristic and minimizes variation in the propagation time caused by increase of the load capacitance.
