The CD4013 or IC-4013 is a CMOS logic chip with two D-Type (DATA) Flip-flops. A clock pulse flow to C (clock pin), will store the data at the D input. Connect clock and a both Q output to make a toggle flip-flop for counting.
For example use them:1HZ Standard digital clock
The importance Pins look at the table below.
1.) Pin 14 is a positive power supply and pin 7 is a ground.
The power supply range of 3 volts to 16 volts and Maximum supply voltage at pin 14 must not much than 18 volts.
1. The first column in the truth table is for the clock input.
They have three states are (1). The rising edge of a clock pulse.
(2.) the falling edge of a pulse, and (3.) Nevermind
The 4013 responds only to a rising edge of a pulse.
Notice that both the R(reset) and S(set) inputs can both be “0” (Low) But not 1 (High-disallowed)
Both the output pin has always different states. If Output 1 is “0” then output 2 is “1”.
Many 4013 circuits
We can use 4013 in many ways. Look at below for example how to use them.
Divide by two
When we enter a signal with a high frequency to the input of IC-4013. It will divide the frequency by two. For example, you enter 1KHz frequency. Then, the output is 500Hz in the same waveform.
