| Standard ICs CMOS logic IC BU4000B The BU4000B Series are CMOS ICs featuring low voltage and low power consumption. The wide range of operating power supply voltages is compatible with the general-purpose 4000B Series, and when a 5V power supply voltage is used, the LS-TTL IC can be driven directly. These ICs are available in SOP and SSOP packages as well as the standard DIP package. *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. *Absolute maximum ratings (Ta = 25C) Parameter Power supply voltage Input voltage Power dissipation3 Storage temperature Symbol VDD VIN Limits - 0.3 ~ + 181 - 0.3 ~ VDD + 0.32 Please refer to specifications for individual package - 55 ~ + 150 Unit V V mW C Pd Tstg 1 For the BU4XXXBC type, VDD = - 0.5 ~ + 20V. 2 For the BU4XXXBC type, - 0.5 ~ VDD + 0.5. 3 The values for the SOP and SSOP packages are the values when mounted on a glass epoxy PCB (50mm x 50mm x 1.6mm). *Recommended operating conditions (Ta = 25C) Parameter Power supply voltage Input voltage Operating temperature Symbol VDD VIN Topr Limits 3 ~ 16 0 ~ VDD - 40 ~ + 85 Unit V V C For the BU4XXXBC type, VDD = 3 to 18V. *Electrical characteristic curves 30 OUTPUT SINK CURRENT: Isink (mA) B Type Ta = 25C 25 VDD = 15V OUTPUT SOURCE CURRENT: Isource (mA) 60 OUTPUT SINK CURRENT: Isink (mA) B Type Ta = 25C 50 30 B Type 25 VDD = 15V - 40C - 5C 20 25C 40C 85C VDD = 10V 40C - - 5C 25C 40C - 40C VDD = 5V - 40C - 5C 25C 40C 85C 5 10 15 20 40 15 10 5 VDD = 5V 0 0 5 10 15 20 25 30 30 20 10 VDD = 5V 0 0 5 10 15 20 25 30 VDD = 15V VDD = 10V 15 10 5 0 0 VDD = 10V 20 25 30 OUTPUT VOLTAGE: VOUT (V) OUTPUT VOLTAGE: VOUT (V) OUTPUT VOLTAGE: VOUT (V) Fig.1 Output sink current vs. output voltage Fig.2 Output source current vs. output voltage Fig.3 Output SINK current vs. output voltage 1 Standard ICs BU4000B 60 OUTPUT SOURCE CURRENT: Isouce (mA) B Type 50 OUTPUT VOLTAGE: VOUT (V) VDD = 15V - 40C - 5C 25C 40C 85C VDD = 10V - 40C - 5C 25C 40C 85C 24 B Type 20 VDD = 15V 85C 25C 40C - 5C - 40C 1500 RISE TIME: tr (ns) 40 16 1000 VDD = 15V 30 20 10 0 0 12 8 VDD = 5V - 40C - 5C 25C 40C 85C 20 25 30 85C 25C 40C - 5C - 40C VDD = 5V 85C 25C 40C - 5C 4 - 40C VDD = 10V 0 0 5 10 15 20 25 30 10V 500 5V 5 10 15 0 INPUT VOLTAGE: VIN (V) 10 100 1000 OUTPUT VOLTAGE: VOUT (V) LOAD CAPACITANCE: CL (pF) Fig.4 Output source current vs. output voltage Fig.5 Output voltage vs. input voltage Fig.6 Rise time vs. load capacitance PROPAGATION DELAY TIME HIGH - TO - LOW LEVEL OUTPUT: tPHL (ns) PROPAGATION DELAY TIME LOW - TO - HIGH LEVEL OUTPUT: tPLH (ns) 1500 VDD = 15V FALL TIME: tf (ns) 1000 10V 1500 1500 1000 VDD = 5V 1000 500 5V 500 10V 500 VDD = 5V 10V 15V 0 10 100 1000 0 10 100 1000 0 10 100 LOAD CAPACITANCE: CL (pF) 15V 1000 LOAD CAPACITANCE: CL (pF) LOAD CAPACITANCE: CL (pF) Fig.7 Fall time vs. load capacitance Fig.8 "H" to "L" propagation delay time vs. load capacitance Fig.9 "L" to "H" propagation delay time vs. load capacitance VDD = 15V 1m 10V 5V MAXIMUM FREQUENCY (MHz) SUPPLY CURRENT: IDD (A) 10 100 CL = 50pF 5 10 10 100k 1M 0 5 10 15 CLOCK FREQUENCY: f (Hz) POWER SUPPLY VOLTAGE: VDD (V) Fig.10 Supply current vs. clock frequency Fig.11 Maximum clock frequency vs. power supply voltage 2 |
