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