| Standard ICs Single OR gate BU4S71 The BU4S71 is an ultra-compact IC with one circuit of the dual-input positive logic OR gate built into an SMP package. *Features dissipation. 1) Low current 2) Super-mini mold package designed for surface mounting. 3) Wide range of operating power supply voltage. 4) Direct drive of 2 L-TTL inputs and 1 LS-TTL input. *Absolute maximum ratings (Ta = 25C) Parameter Power supply voltage Power dissipation Input current Operating temperature Storage temperature Input voltage Symbol VDD Pd IIN Topr Tstg VIN Limits VSS - 0.3 ~ VSS + 18 170 10 - 40 ~ + 85 - 55 ~ + 150 VSS - 0.3 ~ VDD + 0.3 Unit V mW mA C C V Note 1: These values indicate the range limits of the voltage that can be applied to each pin without destroying it. Operation is not guaranteed at these values. Note 2: Reduced by 1.7mW for each increase in Ta of 1C over 25C. *Recommended operating conditions (Ta = 25C, VSS = 0V) Parameter Power supply voltage Input voltage Symbol VDD VIN Min. 3 0 Typ. -- -- Max. 16 VDD Unit V V *Block diagram VDD 5 Y 4 1 A 2 B 3 VSS 1 Standard ICs BU4S71 *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 -- -- - 0.51 Output high level current IOH - 2.1 - 1.3 - 3.4 0.51 Output low level current IOL 1.3 3.4 -- Static current dissipation IDD -- -- Typ. 2.75 5.5 8.25 2.25 4.5 6.75 -- -- 5.0 10.0 15.0 -- -- -- - 1.0 - 4.0 - 2.2 - 9.0 1.2 3.2 12.0 0.001 0.001 0.002 Max. -- -- -- 1.5 3.0 4.0 0.3 - 0.3 -- -- -- 0.05 0.05 0.05 -- -- -- -- -- -- -- 0.25 0.5 1.0 Unit V V V V V V A A V V V V V V mA mA mA mA mA mA mA A A A VDD (V) 5 10 15 5 10 15 18 18 5 10 15 5 10 15 5 5 10 15 5 10 15 5 10 15 VIN = VSS or VDD VOH = 4.6V VOH = 2.5V VOH = 9.5V VOH = 13.5V VOL = 0.4V VOL = 0.5V VOL = 1.5V | IOUT | < 1A VIN = VSS | IOUT | < 1A VIN = VSS or VDD Fig.1 VIH = 18V VIL = 0V | IOUT | < 1A | IOUT | < 1A 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 -- -- -- tPLH Propagation delay time tPHL -- -- -- -- -- Typ. 70 35 30 70 35 30 90 45 30 90 45 30 Max. 200 100 80 200 100 80 200 100 80 200 100 80 Unit ns ns ns ns ns ns ns ns ns ns ns ns VDD (V) 5 10 15 5 10 15 5 10 15 5 10 15 -- -- -- -- Conditions BU4S71 Measurement circuit Fig.2 Fig.2 *Measurement circuits VDD A V VSS Fig. 1 DC characteristics measurement circuit VDD 20ns 90% 50% 10% 20ns Input waveform tPLH P.G tPHL 90% 50% 10% CL = 50pF VSS Output waveform tTLH tTHL Fig. 2 Switching characteristics measurement circuit 3 Standard ICs BU4S71 *External dimensions (Units: mm) 2.9 0.2 (5) (4) 2.8 0.3 1.6 0.2 0.5 (1) (2) (3) 0.4 0.1 0.1 0.1 + 0.05 - 0.95 1.1 0.2 0.05 SMP5 4 |
