MC14518B, MC14520B Dual Up Counters The MC14518B dual BCD counter and the MC14520B dual binary counter are constructed with MOS P−channel and N−channel enhancement mode devices in a single monolithic structure. Each consists of two identical, independent, internally synchronous 4−stage counters. The counter stages are type D flip−flops, with interchangeable Clock and Enable lines for incrementing on either the positive−going or negative−going transition as required when cascading multiple stages. Each counter can be cleared by applying a high level on the Reset line. In addition, the MC14518B will count out of all undefined states within two clock periods. These complementary MOS up counters find primary use in multi−stage synchronous or ripple counting applications requiring low power dissipation and/or high noise immunity. http://onsemi.com SOIC−16 WB DW SUFFIX CASE 751G Features • • • • • • • Diode Protection on All Inputs Supply Voltage Range = 3.0 Vdc to 18 Vdc Internally Synchronous for High Internal and External Speeds Logic Edge−Clocked Design − Incremented on Positive Transition of Clock or Negative Transition on Enable Capable of Driving Two Low−power TTL Loads or One Low−power Schottky TTL Load Over the Rated Temperature Range NLV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable This Device is Pb−Free and is RoHS Compliant MAXIMUM RATINGS (Voltages Referenced to VSS) (Note 1) Parameter Unit −0.5 to +18.0 V −0.5 to VDD + 0.5 V Input or Output Current (DC or Transient) per Pin ±10 mA PD Power Dissipation, per Package (Note 2) 500 mW TA Operating Temperature Range −55 to +125 °C Tstg Storage Temperature Range −65 to +150 °C TL Lead Temperature (8−Second Soldering) 260 °C VDD Vin, Vout Iin, Iout DC Supply Voltage Range Input or Output Voltage Range (DC or Transient) CA 1 16 VDD EA 2 15 RB Q0A 3 14 Q3B Q1A 4 13 Q2B Q2A 5 12 Q1B Q3A 6 11 Q0B RA 7 10 EB VSS 8 9 CB MARKING DIAGRAM Value Symbol PIN ASSIGNMENT 16 145xxB AWLYYWWG 1 xx A WL, L YY, Y WW, W G = 18 or 20 = Assembly Location = Wafer Lot = Year = Work Week = Pb−Free Indicator Stresses exceeding Maximum Ratings may damage the device. Maximum ORDERING INFORMATION Ratings are stress ratings only. Functional operation above the Recommended See detailed ordering and shipping information in the package Operating Conditions is not implied. Extended exposure to stresses above the dimensions section on page 2 of this data sheet. Recommended Operating Conditions may affect device reliability. 1. Maximum Ratings are those values beyond which damage to the device may occur. 2. Temperature Derating: “D/DW” Package: –7.0 mW/_C From 65_C To 125_C This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high−impedance circuit. For proper operation, Vin and Vout should be constrained to the range VSS ≤ (Vin or Vout) ≤ VDD. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must be left open. © Semiconductor Components Industries, LLC, 2014 July, 2014 − Rev. 8 1 Publication Order Number: MC14518B/D MC14518B, MC14520B BLOCK DIAGRAM CLOCK 1 Q0 Q1 Q2 C 2 ENABLE R 3 4 Q3 5 6 Q0 11 Q1 Q2 Q3 12 7 CLOCK 9 C 10 ENABLE R 13 14 15 VDD = PIN 16 VSS = PIN 8 TRUTH TABLE Clock Enable Reset Action 1 0 Increment Counter 0 Increment Counter 0 No Change 0 No Change 0 No Change 0 No Change 1 Q0 thru Q3 = 0 0 X X 0 1 X X X = Don’t Care ORDERING INFORMATION Package Shipping† MC14518BDWG SOIC−16 WB (Pb−Free) 47 Units / Rail MC14518BDWR2G SOIC−16 WB (Pb−Free) 1000 Units / Tape & Reel NLV14518BDWR2G* SOIC−16 WB (Pb−Free) 1000 Units / Tape & Reel MC14520BDWG SOIC−16 WB (Pb−Free) 47 Units / Rail MC14520BDWR2G SOIC−16 WB (Pb−Free) 1000 Units / Tape & Reel Device †For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D. *NLV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable. http://onsemi.com 2 MC14518B, MC14520B ELECTRICAL CHARACTERISTICS (Voltages Referenced to VSS) − 55_C Characteristic Output Voltage Vin = VDD or 0 Symbol 25_C VDD Vdc Min Max Min Typ (Note 3) 125_C Max Min Max Unit “0” Level VOL 5.0 10 15 − − − 0.05 0.05 0.05 − − − 0 0 0 0.05 0.05 0.05 − − − 0.05 0.05 0.05 Vdc “1” Level VOH 5.0 10 15 4.95 9.95 14.95 − − − 4.95 9.95 14.95 5.0 10 15 − − − 4.95 9.95 14.95 − − − Vdc “0” Level VIL 5.0 10 15 − − − 1.5 3.0 4.0 − − − 2.25 4.50 6.75 1.5 3.0 4.0 − − − 1.5 3.0 4.0 5.0 10 15 3.5 7.0 11 − − − 3.5 7.0 11 2.75 5.50 8.25 − − − 3.5 7.0 11 − − − 5.0 5.0 10 15 –3.0 –0.64 –1.6 –4.2 − − − − –2.4 –0.51 –1.3 –3.4 –4.2 –0.88 –2.25 –8.8 − − − − –1.7 –0.36 –0.9 –2.4 − − − − IOL 5.0 10 15 0.64 1.6 4.2 − − − 0.51 1.3 3.4 0.88 2.25 8.8 − − − 0.36 0.9 2.4 − − − mAdc Input Current Iin 15 − ±0.1 − ±0.00001 ±0.1 − ±1.0 mAdc Input Capacitance (Vin = 0) Cin − − − − 5.0 7.5 − − pF Quiescent Current (Per Package) IDD 5.0 10 15 − − − 5.0 10 20 − − − 0.005 0.010 0.015 5.0 10 20 − − − 150 300 600 mAdc IT 5.0 10 15 Vin = 0 or VDD Input Voltage (VO = 4.5 or 0.5 Vdc) (VO = 9.0 or 1.0 Vdc) (VO = 13.5 or 1.5 Vdc) “1” Level VIH (VO = 0.5 or 4.5 Vdc) (VO = 1.0 or 9.0 Vdc) (VO = 1.5 or 13.5 Vdc) Output Drive Current (VOH = 2.5 Vdc) (VOH = 4.6 Vdc) (VOH = 9.5 Vdc) (VOH = 13.5 Vdc) (VOL = 0.4 Vdc) (VOL = 0.5 Vdc) (VOL = 1.5 Vdc) Vdc Vdc IOH Source Sink Total Supply Current (Notes 4, 5) (Dynamic plus Quiescent, Per Package) (CL = 50 pF on all outputs, all buffers switching) mAdc IT = (0.6 mA/kHz) f + IDD IT = (1.2 mA/kHz) f + IDD IT = (1.7 mA/kHz) f + IDD mAdc Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted.
