Abstract
A CMOS driver circuit for integrated circuits capable of operating in two modes. The first, high speed, mode allows the driver circuit on an integrated circuit device to drive the internal signals of the device to the outside world for standard operation of the integrated circuit devices. The second mode causes the driver circuit to behave as a weak driver for easily testing the integrated circuit.
