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. *Logic circuit diagram VDD OUT IN IN VSS *Block diagram 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 1 Standard ICs BU4081B / BU4081BF / BU4081BFV *Absolute maximum ratings (Ta = 25C,V SS Parameter = 0V ) Symbol Limits Unit VDD - 0.3 ~ + 18 V Power supply voltage Pd 1000 (DIP), 450 (SOP), 350 (SSOP) mW Operating temperature Topr - 40 ~ + 85 C Storage temperature Tstg - 55 ~ + 150 C - 0.3 ~ VDD + 0.3 V Power dissipation Input voltage VIN I / O pin current II / O 10 *Electrical characteristics (unless otherwise noted, V Parameter Symbol Min.
