Study of 4 Bit BCD Counter and Decimal to Binary Encoder using IC 7490 Manufacturer,Supplier and Exporter in India
Product Code : JA-SI-1174
This experiment board (SKU JA-SI-1174) is used to study a 4-bit BCD counter and decimal-to-binary encoding with the IC 7490 decade counter, a standard practical in engineering, polytechnic and diploma digital electronics courses. Students connect the divide-by-2 and divide-by-5 sections of the IC to obtain the 0 to 9 count, read the 4-bit BCD output, and use the reset and set-to-9 inputs.
