How to build Frequency Divider with 7490

Description

Here you will find a interesting collection from frequency dividers with division factor from 2 until 10. All the choices they are based in the 7490 that are a Decade and Binary Counter. If two 7490 are connected in cascade then we can achieve division factor of frequency of input of proportional factor each 7490. The voltage supply it‘s + 5V.
