SEMICONDUCTOR INTEGRATED CIRCUITRY

摘要

The LSI uses diodes and transistors. These include an input transistor (5) coupled at its base to the input line via a Schottky barrier layer diode (7) its collector coupled to the operating voltage (14) and the base of a second transistor (3) and its emitter coupled to the base of a third transistor (6). Two further Schottky diodes (18, 1) are coupled across the collector and base and the emiter and base of a fourth transistor (4) connected as an emitter follower for the second transistor (3) and lying in series with an emitter follow transistor (2) for the first transistor (5). ADVANTAGE-Increased breakdown voltage level.
