Out of stock4017 Decade Counter IC
[Timer,Clock,Counter ICs] DESCRIPTION:- This IC 4017 is a 16-pin counter IC. It is a CMOS decade counter cum decoder circuit. It can count from zero to ten and its outputs are decoded. This saves a lot of board space and time required to build our circuits when our application demands using a counter followed by a decoder IC. IC 4017 is a digital counter plus decoder circuit. CD4017 Pin Configuration :- Pin Number Pin Name Description 1 to 7 and 9,10,11 Output pins Q0 to Q9 These are the 10 output pins on which the counting occurs, they are not in order hence verify pin diagram above 8 Vss or Ground Connected to the Ground of the circuit 12 Carry Out (CO) This pin goes high after the IC counts from 1 to 10. This is used as carry while counting. 13 Clock Enable (EN) This is an input which when made high will hold the count at the current state 14 Clock The counting happens when this clock pulse goes high , this pin is normally connected to 555 timer or other uC to produce a pulse 15 Resets As the name suggests this pin resets the count back to 1 16 Vdd / Vcc Connects to the supply voltage typically +5V Features:- High speed 16 pin CMOS Decade counter Supports 10 decoded outputs Wide supply voltage range from 3V to 15V, typically +5V TTL compatible Maximum Clock Frequency: 5.5Mhz Available in 16-pin PDIP, GDIP, PDSO packages Where to use CD4017 IC:- The IC CD4017 is used for counting applications, it has the capability to turn on 10 outputs sequentially in a pre-defined time and reset the count or hold it when required. It also has the capability to indicate the status of counting using Carry pin. This is commonly used for Led chasers and other logical output projects, so if you are looking for a sequential decoded counting IC that can count up to 10 then this IC will be your right choice How to use a CD4017 IC:- The IC can work from 3V to 15V, but normally powered with +5V to the Vdd/Vcc pin and the Ground/Vss pin is connected to ground. We have 10 output pins ranging from Q0 to Q9, these pins can be connected to any load but we are using LEDs here as shown in the circuit below. Package Includes :- 1 X 4017 Decade Counter IC
