No Preview Available ! MOTOROLA SEMICONDUCTOR TECHNICAL DATA Decade Counter The MC14017B is a five–stage Johnson decade counter with built–in code converter. High speed operation and spike–free outputs are obtained by use of a Johnson decade counter design. The ten decoded outputs are normally low, and go high only at their appropriate decimal time period. The output changes occur on the positive–going edge of the clock pulse. This part can be used in frequency division applications as well as decade counter or decimal decode display applications. • Fully Static Operation • DC Clock Input Circuit Allows Slow Rise Times • Carry Out Output for Cascading • Divide–by–N Counting • 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 • Pin–for–Pin Replacement for CD4017B ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ• Triple Diode Protection on All Inputs ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎMAXIMUM RATINGS* (Voltages Referenced to VSS) Symbol Parameter Value Unit ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎVDD DCSupplyVoltage ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎVin, Vout Input or Output Voltage (DC or Transient) ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎlin, lout Input or Output Current (DC or Transient), per Pin – 0.5 to + 18.0 – 0.5 to VDD + 0.5 ± 10 V V mA ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎPD Power Dissipation, per Package† ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎTstg Storage Temperature ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎTL Lead Temperature(8–SecondSoldering) 500 – 65 to + 150 260 mW _C _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 Q5 Q1 12 Q7 Q3 Q9 67 11 14 CLOCK CLOCK ENABLE 13 15 RESET CQ C DQ RR CQ C DQ RR CQ C DQ RR CQ C DQ RR CQ C DQ RR 12 CARRY REV 3 1/94 ©MMCot1or4o0la1, I7nBc. 1995 74 3 5 4 9 10 Q0 Q6 Q2 Q3 Q4 MC14017B L SUFFIX CERAMIC CASE 620 P SUFFIX PLASTIC CASE 648 D SUFFIX SOIC CASE 751B ORDERING INFORMATION MC14XXXBCP MC14XXXBCL MC14XXXBD Plastic Ceramic SOIC TA = – 55° to 125°C for all packages.
