This was the first edition of th. Interesting, it’s a decade counter; but what is a decade counter? Jc grants anyone the right to use this work for any purposewithout any conditions, unless such conditions are required by law. It appears, that there is a count up mode.
4-Bit Binary Decade Up/Down Counter using IC 74192
Let’s first look at the 74LS; a quick google search will yield the datasheet on the first hit: However, since you are probably not accustomed I admit, I’m not ideal at reading them to going through datasheets, I’ll try to guide you through some logic:. We do require a clock for the 74LS As echad said look at 74912 datasheets and have a go at a schematic of a and 74LS connected together.
