| 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 dissipation. 1) Low power 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. *Block diagram A1 1 14 VDD B1 2 13 A4 O1 O2 3 4 12 B4 11 O4 B2 5 10 O3 A2 VSS 6 7 9 B3 8 A3 *Absolute maximum ratings (VSS = 0V, Ta = 25C) Parameter Power supply voltage Power dissipation Operating temperature Storage temperature Input voltage Symbol VDD Pd Topr Tstg VIN Limits - 0.3 ~ + 18 1000 (DIP), 450 (SOP) - 40 ~ + 85 - 55 ~ + 150 - 0.3 ~ VDD + 0.3 Unit V mW C C V 1 Standard ICs BU4001B / BU4001BF *Electrical characteristics otherwise noted, VSS = 0V, Ta = 25C) DC characteristics (unless 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 Switching characteristics (unless otherwise noted, VSS = 0V, Ta = 25C, CL = 50pF) Parameter Symbol Min. -- Output rise time tTLH -- -- -- Output fall time tTHL -- -- -- Propagation delay time, "L" to "H" tPLH -- -- -- Propagation delay time, "H" to "L" Input capacitance tPHL -- -- CIN -- Typ. 180 90 65 100 50 40 90 50 40 90 50 40 5 Max. -- -- -- -- -- -- -- -- -- -- -- -- -- pF ns ns ns ns Unit BU4001B / BU4001BF VDD (V) 5 10 15 5 10 15 5 10 15 5 10 15 -- Conditions Measurement circuit -- Fig.2 -- Fig.2 -- Fig.2 -- Fig.2 -- -- *Measurement circuits VDD VDD 20ns 90% Input A tPHL V P.G 20ns 50% 10% 90% 50% 10% tPLH CL = 50pF Output GND GND tTHL tTLH Fig.1 DC characteristics Fig.2 Switching characteristics *Electrical characteristic curve 1200 POWER DISSIPATION: Pd (mW) 1000 800 DIP14 600 SOP14 400 200 0 0 25 50 75 100 125 150 AMBIENT TEMPERATURE: Ta (C) Fig.3 Power dissipation vs. Ta characteristic 3 Standard ICs BU4001B / BU4001BF *External dimensions (Units: mm) BU4001B BU4001BF 8.7 0.2 6.5 0.3 8 14 6.2 0.3 4.4 0.2 8 19.4 0.3 14 1 4.25 0.3 0.51Min. 7 7.62 1.5 0.1 1 7 0.11 3.2 0.2 0.3 0.1 1.27 0.4 0.1 0.3Min. 0.15 2.54 0.5 0.1 0 ~ 15 DIP14 SOP14 4 0.15 0.1 |
