CD4017BE CMOS Counter/Divider IC

The CD4017BE is a pop­u­lar CMOS decade counter that pro­duces 10 sep­a­rate out­puts in sequence. Every time it receives a clock pulse, it turns off the cur­rent out­put and turns on the next one. It is famous for cre­at­ing “chase” light­ing effects and is wide­ly used in tim­ing and count­ing projects because it can be eas­i­ly con­nect­ed to LEDs or oth­er dig­i­tal com­po­nents.Key Features10-Out­put Sequence: Auto­mat­i­cal­ly cycles through 10 indi­vid­ual out­put pins.Ful­ly Syn­chro­nous: Moves to the next step pre­cise­ly with each clock pulse.Reset Func­tion: Includes a ded­i­cat­ed pin to start the count back from zero at any time.Clock Inhib­it: Fea­tures a con­trol pin to “freeze” the cur­rent count.Wide Volt­age Range: Works reli­ably with pow­er sup­plies from 3V up to 18V.Low Pow­er Con­sump­tion: Effi­cient CMOS design, ide­al for bat­tery-pow­ered hob­by projects.Typical ApplicationsLED Chasers: Cre­at­ing sequen­tial light pat­terns (like the “Knight Rid­er” effect).Fre­quen­cy Divi­sion: Divid­ing an input clock sig­nal by any num­ber from 2 to 10.Dig­i­tal Timers: Used as a build­ing block for clocks and count­down timers.Remote Con­trol Decod­ing: Trans­lat­ing puls­es into spe­cif­ic actions or com­mands.Bina­ry Count­ing: Serv­ing as a sim­ple dec­i­mal counter for edu­ca­tion­al elec­tron­ics kits.DATASHEET
