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. •1)Features Low power dissipation. 4) High fan-out. 5) Direct drive of 2 L-TTL inputs and 1 LS-TTL input. 2) Wide range of operating power supply voltage. 3) High input impedance. •Block diagram •Absolute maximum ratings (V Parameter SS A1 1 14 VDD B1 2 13 A4 O1 3 12 B4 O2 4 11 O4 B2 5 10 O3 A2 6 9 B3 VSS 7 8 A3 = 0V, Ta = 25°C) Symbol Limits Unit Power supply voltage VDD – 0.3 ~ + 18 V Power dissipation Pd 1000 (DIP), 450 (SOP) mW Operating temperature Topr – 40 ~ + 85 °C Storage temperature Tstg – 55 ~ + 150 °C – 0.3 ~ VDD + 0.3 V Input voltage VIN 1 Standard ICs BU4001B / BU4001BF characteristics •DCElectrical characteristics (unless otherwise noted, V SS Parameter Input high level voltage Symbol Min.
