Quad 2-input NAND gate
BU4011B / BU4011BF / BU4011BFV
The BU4011B, BU4011BF, and BU4011BFV are dual-input positive logic NAND gates.
Four circuits are contained on a single chip. An inverter-based buffer has been added to the gate output, enabling
improved input / output propagation characteristics, and an increased load capacitance minimizes fluctuation in prop-
agation time.
