The basic multiplexer circuit consists of several input lines, a control input line, and a single output line. The control input line is used to select which input line is connected to the output line. When the control input is set to a certain value, the corresponding input signal is passed through to the output line, while all other input signals are blocked. Manufacturers : Toshiba |
