ABSTRACT:
A semiconductor integrated circuit device with an ECL sequential circuit is disclosed, which comprises a data holding circuit provided the ECL sequential circuit for holding the output thereof, and an emitter follower for feeding the output of the data holding circuit as an input thereof, and an emitter follower circuit control circuit thereto. The emitter follower current when the emitter potential on the emitter follower is at a high level, is set to be lower than the emitter follower current when the emitter potential is at a low level.
