Abstract
A circuit for clamping the base of an output pull-down transistor includes a clamp transistor connecting the base of the pull-down transistor to a ground node and a drive circuit for rapidly turning on the clamp transistor in response to a high-to-low transition on an input node. The drive circuit includes a string of Schottky diodes connecting the base of the clamp transistor to the collector of a transistor whose base is responsive to the voltage on the input node.
