Abstract
A TTL-CMOS output stage for an integrated circuit includes a bipolar transistor and a MOS transistor series connected between the power supply and ground, their common point forming the output terminal of the TTL-CMOS output stage. A first switching control input channel includes an inverter whose input forms the input terminal of the stage and whose output is connected to the gate of the MOS transistor via a resistor. A second switching control input channel includes a second inverter controlled by the first inverter and whose output is connected to the base of the bipolar transistor by means of a second resistor. The resistors make it possible to limit the transient current and the mean current supplied by the bipolar transistor.
