Abstract
A two terminal monolithic integrated clamp circuit includes first and second circuits coupled between the two input terminals thereof for clamping the voltage appearing across the two terminals to a predetermined voltage. The first circuit is responsive to the voltage level appearing at the first terminal exceeding the voltage level at the second terminal by said predetermined amount for clamping the voltage level thereat while shunting the majority of the current through the clamping circuit to substrate ground of the integrated circuit. The second circuit is responsive to the voltage level appearing at the second terminal exceeding the voltage level at the first terminal by said predetermined amount for clamping the voltage thereat while shunting the majority of the current to substrate ground.
