Digital Clock Circuit Diagram Using 7490. Its count always in the upward direction in increasing order that s why it is also known as up counter. It s long not pretty and doesn t exist meaning i haven t made one.
Many approach and design are available online but implementing it using 7490 decade counter is one of the easiest design. Best application and uses of logic gates with practical examples. Please refer to the diagram below for the appropriate circuit.
Please see attached file.
I was just wondering if anyone could verify my schematic if the circuit would work out smoothly. Please refer to the diagram below for the appropriate circuit. Connect qa qb qc and qd from a 7490 to pins 7 1 2 and 6 of the 7447 respectively. Best application and uses of logic gates with practical examples.
