ABSTRACT:
A circuit for interfacing a digital to analog converter with input signals from three different logic systems, whereby appropriate threshold switching signals compatible with each logic system are presented to the converter when the proper logic control signal is applied to the circuit. The first logic system is characterized by logic control signals within a first voltage range, and switching thresholds which differ from the logic control signals by a fixed increment; the second system by logic control signals within a second voltage range higher than the first range, and switching thresholds equal to a fixed proportion of the logic control signal; and the third system by a substantially constant switching threshold for a predetermined positive supply voltage level.
