Abstract
A circuit which provides additional drive current during substantially the entire transition of an output signal from a logical one to a logical zero state, thereby causing the pulldown transistor in the TTL output stage to rapidly turn on, providing increased switching speed between logical one and logical zero output state for a given power consumption. Alternatively, for a given switching speed, power consumption is reduced.
