Abstract
A high speed logic gate is disclosed in which the voltage across the output transistor is clamped by a diode, a current switch transistor, a resistor connected between the diode and the transistor and a resistor connected to ground. A selectable high impedance is provided to enable the output of the logic gate to simulate an open collector output.
