The MR (Master Reset) of datasheet binary counter must be pulled down at any time, leaving it open might cause unpredictable results at the leds might blink randomly.
We will discuss datasheet more about that in the working part.
Features, counter high counter speed 16 pin cmos Decade counter.
A decimal counter is a chip designed to count the number of counter pulses or events that occur in digital circuits.
The timing diagram of the IC indicating the state of Output pins and Carry pin for every high pulse signal counter is shown below.The circuit starts at clock pin, here we pull down the clock pin to ground through a 1K datasheet resistor.The capacitor is for neutralizing the bouncing effect of the button.Clock with LED Pendulum, heart Shape datasheet LED Flasher.
To reset the counter to zero under any stage connect the MR pin of counter to 5V, this resets the counter to zero.
Now calculadora counter the clock is provided with a button, school so for every button press there will be a positive peak at the clock pin and hence an event. .
Output omega 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.

This is to be done because the binary counter is a rising edge type.In the absence of capacitor, the counter may count the events occurring wrongly.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.Components Required, power supply (5v) 1K, 220 resistors.Here we are going to use a 10 bit decade counter.And for the output it provides the event number as binary output through pins 3,2,4,7,10,1,5,6,9,11,12.13 clock enable should be grounded for the chip to count the events or clock pulses, the pin no 12 carry OUT is for next counter chip, this pin is connected to next chip clock pin if we were to increase the counter capacity.These pins are held low (0V/grounded) by default, but when the Clock Enable game pin is made high the counting pauses.PIN8, PIN15, PIN13 to Ground, pIN14 to Button, pIN1 to Ground through 1k resistor.These counters have limitations for working voltage and clock frequency.So if the event count is seven the pin 6will be high and so the corresponding LEDs glow.Arduino, PIC etc to generate our custom pulse using I/O pins.For example if the count was at pin Q3 when the Clock enable pin was made high, then the count will pause at pin Q3 irrespective of any high pulses from clock and will continue incrementing only when Clock Enable is made low again.
