ABSTRACT:
An encoder circuit is disclosed wherein a plurality of input signals are parallel-supplied directly to the gates of transistor pairs. Each transistor pair comprises at least two series-connected transistors which are provided between an associated one of output lines and a source of a predetermined potential level (a supply potential or groud potential). The encoding function of the circuit is performed by turning on and off the transistors.
