1 / 6 page MOTOROLA CMOS LOGIC DATA 87 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. • 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 MAXIMUM RATINGS* (Voltages Referenced to VSS) Symbol Parameter Value Unit VDD DC Supply Voltage – 0.5 to + 18.0 V Vin, Vout Input or Output Voltage (DC or Transient) – 0.5 to VDD + 0.5 V lin, lout Input or Output Current (DC or Transient), per Pin ± 10 mA PD Power Dissipation, per Package† 500 mW Tstg Storage Temperature – 65 to + 150 _C TL Lead Temperature (8–Second Soldering) 260 _C * Maximum Ratings are those values beyond which damage to the device may occur. †Temperature Derating: Plastic “P and D/DW” Packages: – 7.0 mW/ _C From 65_C To 125_C Ceramic “L” Packages: – 12 mW/ _C From 100_C To 125_C LOGIC DIAGRAM CLOCK RESET 11 10 Q1 Q4 Q5 Q12 Q13 Q14 9 7 5 1 2 3 C C R Q Q C C R Q Q C C R Q Q C C R Q Q C C R Q Q C C Q R Q6 = PIN 4 Q7 = PIN 6 Q8 = PIN 13 Q9 = PIN 12 Q10 = PIN 14 Q11 = PIN 15 VDD = PIN 16 VSS = PIN 8 MOTOROLA SEMICONDUCTOR TECHNICAL DATA © Motorola, Inc. 1995 REV 3 1/94 MC14020B L SUFFIX CERAMIC CASE 620 ORDERING INFORMATION MC14XXXBCP Plastic MC14XXXBCL Ceramic MC14XXXBD SOIC TA = – 55° to 125°C for all packages.
