Abstract
A current driver circuit (10) sources current to an output node (N4) in response to an input signal (VI) being a logic high. The current driver circuit (10) utilizes a current source (16) which sinks current from the output node (N4) in response to the input signal (VI) switching from a logic high to a logic low. The current source (16) is deactivated for a predetermined time delay after the input signal (Vi) switches from a logic high to a logic low.
