Abstract

In many circuits, the critical timing of the logic lays primarily in one edge. The drawing illustrates a circuit that sinks a current from a load during aITL low input and removes the current very rapidly during a positive edge. The speed is contributed to: (1) Thediffusion capacitance of the input pnp translates the input edge instantaneously.
