Clock generator circuit based NAND gate CMOS IC 4011 or TTC IC 7400.
– Excellent clock generator to drive 4017 type CMOS circuits.
– R1 = 10K to 10M, C1 = 100pF to 47uF.
– Fo is ± 1KHz when R1 = 100K and C1 = 10nF.
– You must use regulated 5V input voltage for 7400, while CMOS 4011 can be from 5 to 15V. Regulated power supply with LM7805 will be great to supply this circuit (with 7400).

In the electrical sector, a schematic diagram is usually used to describe the design or model of equipment. Schematic diagrams are usually utilized for the maintenance and repair of electronic and electromechanical devices / units. Original schematics were made by hand, using standardized templates or pre-printed adhesive symbols, but nowadays Electrical CAD computer software is often used.
In electronic design automation, until the 1980s schematics were virtually the only formal representation for circuits. More lately, using the progress of computer system technology, other representations were introduced and specialized computer languages were developed, because with the explosive development of the complexity of electronic circuits, classic schematics are getting less practical. As an example, hardware description languages are indispensable for contemporary digital circuit design.
