ABSTRACT:
Low voltage, low power transistor driver/receiver and logic circuits are disclosed comprising a pair of NPN transistors, the base of the first transistor being directly connected to an input terminal and, via a resistor, to the base of the second transistor. A third NPN transistor is connected with the second transistor in series circuit across a low voltage power supply. The junction between the series-connected transistors is coupled to an output terminal. A diode is connected between a point on the resistor and the collector of the second transistor to prevent saturation. The emitter of the second transistor is connected through a small or zero resistance to one terminal of the power supply. The down level at the output terminal is held by a transistor or diode clamp connected between the base of the third transistor and the other terminal of the power supply.
Various embodiments of the circuits are disclosed to provide driver and logic functions and to permit tailoring of the circuits to various load conditions requiring different output signal swing amplitudes and different response times.
