Jun 15, 2010 · I am having some problems trying to create a circuit for a 12 Hour digital clock circuit using 74LS90 IC's and 6x 7 segment displays to show the hours, minutes and seconds. I need the clock to have a start / stop and a reset function. Attached to this post is a screen shot of the circuit that I have so far, using the 7490 IC's.

All the part names for which the file 375734_DS.pdf is a datasheet The upper image use a circuit that is called switch debounce. A switch debounce can be software or hardware. We will create the latter. The circuit below is a RS latch that is used as a switch debouncer. It's composed by two 2-input NAND gates with outputs feedbacks to the input of another.

Fairchild does not assume any responsibility for use of any circuitry described, no circuit patent licenses are implied and Fairchild reserves the right at any time without notice to change said circuitry and specifications. LIFE SUPPORT POLICY FAIRCHILD’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT This is because in the circuit the output of X8 is given as the input to the NOT gate 7404 IC. And the output which is inverted is given back as an input to IC 74164. Hence Johnson counter is also called as Inverse feedback counter. If you have any doubt in the circuit please leave a comment we will respond you. 🙂
