Working Principles

The MM74C914N is a digital-to-analog converter (DAC) that operates by converting binary input data into corresponding analog voltages. The address inputs (A0-A7) are used to select the desired digital value, which is then converted into an analog voltage at the OUT pin. The WR and CS inputs control the write operation and chip select, respectively.
