The HV3922 is a monolithic high-voltage quad-output driver that is designed to be used in conjunction with the Supertex VN2222NC*, a separate N-channel DMOS FET quad array, whose device characterics are briefly described below. Together, these devices per-form a 220V push-pull function that is especially suited for driving PIN diodes in applications such as frequency-hopping radios, microwave communication systems and phased array radar.
