4 Bit Magnitude Comparator Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12743
Indian Lab Suppliers supplies the 4 Bit Magnitude Comparator (Product ID: 12743) as part of its electronics engineering lab equipment range. It demonstrates the 4-bit magnitude comparator IC 7485, which decides whether one binary number is greater than, equal to or less than another.
Quick Answer
Two 4-bit numbers A and B are set with SPDT toggle switches, each with an LED showing its state, and three output LEDs show A > B, A = B and A < B. Students work out the internal logic of the 7485 and how to connect it with other components, such as cascading for longer words. The board has a built-in 5 V DC, 100 mA regulated supply, mains ON/OFF switch, fuse and jewel light, and sockets for voltage measurements. Please confirm the mains supply voltage at quotation.
