Study of Decade Counter using ICs 7490 & 7493 Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12704
Indian Lab Suppliers supplies the Study of Decade Counter using ICs 7490 & 7493 (Product ID: 12704) as part of its electronics engineering lab equipment range. It studies decade counting with the IC 7490 in two modes and with the 4-bit binary counter IC 7493.
Quick Answer
The 7490 is wired first in 2 × 5 mode, where the divide-by-2 stage feeds the divide-by-5 stage to give a BCD count, and then in 5 × 2 mode, where the order is reversed and the last output becomes a symmetrical divide-by-10 square wave. The 7493 4-bit binary counter is made into a decade counter by direct clearing, using the 4-input AND gate and inverters to reset it at the count of ten. A pulser provides the clock and a two-digit seven-segment display with decoder shows the count in decimal. It runs from 230 V ±10%, 50 Hz mains with an internal IC-regulated 5 V, 100 mA supply, fuse and jewel light. Operating instructions with theory and report suggestions, and 4 mm stackable patch cords, are supplied.
