| 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. *Features dissipation. 1) Low power 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 13 A4 12 B4 11 O4 10 O3 9 B1 2 O1 3 O2 4 B2 5 A2 6 B3 VSS 7 8 A3 1 Standard ICs BU4081B / BU4081BF / BU4081BFV *Absolute maximum ratings (Ta = 25C,VSS = 0V ) Parameter Power supply voltage Power dissipation Operating temperature Storage temperature Input voltage I / O pin current Symbol VDD Pd Topr Tstg VIN II / O Limits - 0.3 ~ + 18 1000 (DIP), 450 (SOP), 350 (SSOP) - 40 ~ + 85 - 55 ~ + 150 - 0.3 ~ VDD + 0.3 10 Unit V mW C C V mA *Electrical characteristics (unless otherwise noted, VSS = 0V, Ta = 25C) Parameter Symbol Min. 3.5 Input high level voltage VIH 7.0 11.0 -- Input low level voltage VIL -- -- Input high level current Input low level current IIH IIL -- -- 4.95 Output high level voltage VOH 9.95 14.95 -- Output low level voltage VOL -- -- - 0.16 Output high level current IOH - 0.4 - 1.2 0.44 Output low level current IOL 1.1 3.0 -- Static current dissipation IDD -- -- Typ. -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Max. -- -- -- 1.5 3.0 4.0 0.3 - 0.3 -- -- -- 0.05 0.05 0.05 -- -- -- -- -- -- 1 2 4 A mA mA V V A A V V Unit VDD (V) 5 10 15 5 10 15 15 15 5 10 15 5 10 15 5 10 15 5 10 15 5 10 15 VI = VDD or GND -- VOH = 4.6V VOH = 9.5V VOH = 13.5V VOL = 0.4V VOL = 0.5V VOL = 1.5V Fig.1 Fig.1 IO = 0mA Fig.1 IO = 0mA Fig.1 VIH = 15V VIL = 0V Fig.1 Fig.1 -- Fig.1 -- Fig.1 Conditions Measurement circuit 2 Standard ICs BU4081B / BU4081BF / BU4081BFV Switching characteristics (unless otherwise noted, VSS = 0V, Ta = 25C, CL = 50pF) Parameter Symbol Min. -- Output rise time tTLH -- -- -- Output fall time tTHL -- -- -- "L" to "H" Propagation delay time tPLH -- -- -- "H" to "L" Propagation delay time Input capacitance tPHL -- -- CIN -- Typ. 180 90 65 100 50 40 160 65 50 160 65 50 5 Max. -- -- -- -- -- -- -- -- -- -- -- -- -- pF ns ns ns ns Unit Conditions Measurement circuit VDD (V) 5 10 15 5 10 15 5 10 15 5 10 15 -- -- Fig.2 -- Fig.2 -- Fig.2 -- Fig.2 -- -- *Measurement circuits VDD A V GND Fig. 1 DC characteristics VDD 20ns 90% 50% Input waveform 10% P.G.
