ABSTRACT:
A semiconductor device such as an ECL gate array having emitter-follower-type output transistors, wherein protective elements are arranged between input/output pads and a power supply line connected to the collectors of the emitter-follower-type output transistors, whereby wiring between the protective elements and the power supply line become unnecessary so that the manufacturing process becomes easy and the integration degree is improved while a large tolerance voltage is maintained against destruction due to static electricity.
