1 / 8 page © Semiconductor Components Industries, LLC, 2005 August, 2005 − Rev. 6 1 Publication Order Number: MC14020B/D MC14020B 14−Bit Binary Counter The MC14020B 14−stage binary counter is constructed with MOS P−Channel and N−Channel enhancement mode devices in a single monolithic structure. This part is designed with an input wave shaping circuit and 14 stages of ripple−carry binary counter. The device advances the count on the negative−going edge of the clock pulse. Applications include time delay circuits, counter controls, and frequency−dividing circuits. Features • Fully Static Operation • Diode Protection on All Inputs • Supply Voltage Range = 3.0 Vdc to 18 Vdc • Capable of Driving Two Low−power TTL Loads or One Low−power Schottky TTL Load Over the Rated Temperature Range • Buffered Outputs Available from stages 1 and 4 thru 14 • Common Reset Line • Pin−for−Pin Replacement for CD4020B • Pb−Free Packages are Available* MAXIMUM RATINGS (Voltages Referenced to VSS) Symbol Parameter Value Unit VDD DC Supply Voltage Range −0.5 to +18.0 V Vin, Vout Input or Output Voltage Range (DC or Transient) −0.5 to VDD + 0.5 V Iin, Iout Input or Output Current (DC or Transient) per Pin ±10 mA PD Power Dissipation, per Package (Note 1) 500 mW TA Ambient Temperature Range −55 to +125 °C Tstg Storage Temperature Range −65 to +150 °C TL Lead Temperature (8−Second Soldering) 260 °C Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. 1. Temperature Derating: Plastic “P and D/DW” Packages: – 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 v (Vin or Vout) v 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. *For additional information on our Pb−Free strategy and soldering details, please download the ON Semiconductor Soldering and Mounting Techniques Reference Manual, SOLDERRM/D. http://onsemi.com MARKING DIAGRAMS PDIP−16 P SUFFIX CASE 648 MC14020BCP AWLYYWW SOIC−16 D SUFFIX CASE 751B TSSOP−16 DT SUFFIX CASE 948F 14020B AWLYWW 14 020B ALYW A = Assembly Location WL, L = Wafer Lot YY, Y = Year WW, W = Work Week SOEIAJ−16 F SUFFIX CASE 966 MC14020B ALYW See detailed ordering and shipping information in the package dimensions section on page 2 of this data sheet.
