ABSTRACT:
A flip-flop circuit of ECL structure includes an ECL circuit portion and a level shift circuit portion including a circuit having a pair of resistors. The ECL circuit portion applies a differential signal to one end of each of the resistors, and Q and/Q output signals are derived from the other ends of each of the resistors. The amount of level shift down of the signals when shifted by the resistors is enabled to be set to any relatively small amount, whereby the ECL circuit is permitted to operate at a low voltage.
