Overview
Standard ICs 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.
