Ic 74138 Pin Diagram And Truth Table. Ic 7483 consists of four individual full adder circuits which are internally connected. If the output is high h led corresponding to that output will turn on.
Voltage at a control enable or select pin will be high h if the switch corresponding to that control enable or select pin is off.
