multi-bit counter circuit used to performance

Published:2011/5/16 18:44:00 Author:Christina | Keyword: multi-bit counter, performance | From:SeekIC

This counter circuit can be used in the demonstration teaching and the science and technology exhibition applications, every bit of this counter is composed of the decimal counter RS7490, the RS7447 decoder and the 7 segment digital tube. If you want to add two stages more, the monitor must gets to the number of 9999 to start a new count cycle. The diode 1N914 which connects with the battery can be used to prevent the wrong polarity of power supply, and you need to reduce the power supply voltage to 5V to meet the integrated circuit's need.
