How does a decade counter work?
The basic decade counter is an electronic circuit with a 4-bit binary output and an input signal (called a clock). With each clock pulse the outputs advance to the next higher value, resetting to 0000 when the output is 1001 and a subsequent clock pulse is received.
What is OE pin?
OE (Output Enable) is an output enable signal and read data is output from a data pin when it is set at low level. The function and name are the same as for OE of the EPROM.
What is active high and low?
Active low means the active portion is at 0V, so 0% duty cycle when active low will leave the output at the supply volts (3.3V or 5V, depending what Vcc you use) Active high means the output will be at the supply voltage for the active portion, and then 0% duty cycle will leave the output at 0V.
How does an IC work in a circuit?
An IC can function as an amplifier, oscillator, timer, counter, logic gate, computer memory, microcontroller or microprocessor. An IC is the fundamental building block of all modern electronic devices.
What is a 4017 clock circuit?
As an electronic circuit, the IC 4017 can add from 0-9 (10). That’s why it’s called the decade counter. Also, the output from this circuit comes in decoded format. Also, this circuit has ten outputs, and they come with a high sequence in response to a high clock pulse.
What are the features of IC 4017?
Here are some of the features of the IC 4017: You can use the IC 4017 for electronic devices, alarms, automotive devices, and even electronic instrumentation devices The IC 4017 has 16 pins that serve different purposes. So, ten pins serve as output pins, while the other six pins are input pins.
How does 4017 IC Blink the LEDs in sequence?
Then 4017 IC will blink the LEDs in sequence as per the signal in the clock pin (14). This the schematic of the 10 LED chaser with only 4017 IC.
How to make simple led chaser circuit using cd4017 IC?
To make this simple LED chaser circuit I have used only a 4017 IC. Here the flashing RGB LED will generate the clock pulse for CD4017 IC. Then 4017 IC will blink the LEDs in sequence as per the signal in the clock pin (14).
