Quad 2-input AND gate
BU4081B / BU4081BF / BU4081BFV
The BU4081B, BU4081BF, and BU4081BFV are dual-input positive-logic AND gates with four circuits mounted on a
single chip. An inverter-type buffer is added to the gate output, improving input / output transmission speed, and an
increased load capacitance suppresses fluctuation in transmission time to a minimum.
