To Study the Characteristics and Operation of a Programmable Counter Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12698
Indian Lab Suppliers supplies the To Study the Characteristics and Operation of a Programmable Counter (Product ID: 12698) as part of its electronics engineering lab equipment range. It studies the up, down and preset modes of a programmable counter built on the IC 74193.
Quick Answer
The 74193 is a presettable 4-bit synchronous up/down binary counter with carry and borrow outputs. Students run it in up mode and watch the carry pulse, in down mode and watch the borrow pulse, and load a preset value from the logic switches before counting. A pulser switch clocks the counter, push switches give clear and load, and two seven-segment displays with decoder show 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.
