ROHM BU4081B/BF/BFV

Standard ICs
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.
•1)Features
Low power dissipation.
2) Wide range of operating power supply voltages.
3) High input impedance.
4) High fan-out.
5) Direct drive of 2 L-TTL inputs and 1 LS-TTL input.
