Document Type and Number:
Japanese Patent JPH05504832
Kind Code:
A
Abstract:
A driver circuit is disclosed for use in testing bi-directional transceiver semiconductor products using a minimum of time and number of product accessing pins. The driver includes a pair of controllable amplitude current sources whose output currents are selectably switched into or partially away from the commonly connected emitters of a current switch. The current switch is energized by a variable voltage source and produces the output test voltage.
