Abstract
An integrated circuit comprises a first input node and a second input node, an output node; a first output transistor of a first type and a second output transistor of a second type, and a first clamping transistor of the second type and a second clamping transistor of the second type. The first clamping transistor, the first output transistor, the second clamping transistor, and the second output transistor are coupled in series across a first power supply terminal and a second power supply terminal. The first input node is coupled to a gate of the first output transistor. The second input node is coupled to a gate of the second output transistor. The output node is coupled to a common node of the first output transistor and the second clamping transistor. A gate of the first clamping transistor is coupled to a first reference voltage. A gate of the second clamping transistor is coupled to a second reference voltage.
