ABSTRACT:
Disclosed herein is a flip/flop circuit of a master-slave type including master side and slave side latch/hold circuits 1 and 2 each being of an ECL vertical 1-step construction, first and second bias circuits 3 and 4 for biasing current sources Tr's 21 to 24 of these latch/hold circuits 1 and 2 and a control circuit 5 for pull-down controlling these first and second bias circuits 3 and 4 by clock signals. The current sources Tr's 21 to 24 are thus selectively rendered conductive and non-conductive to perform a flip-flop operation on a low power source voltage such as 1V or less.
