LATCH DRIVER CIRCUIT AND STRUCTURE FOR A GAS PANEL DISPLAY Abstract The circuit and structure of a high voltage switch with latchup is disclosed for a latching driver used in a gas panel display. The driver circuit functions as a high voltage, single pole, double throw switch with memory. A plurality of the latch- ing driver circuits may be integrated on an LSI chip. Each posi- tion lighted on a gas panel display requires two latching driver circuits which are operated in a complementary fashion by suit- able logic. The latching driver circuit is comprised of a com- plementary transistor, high voltage output switch which is con- trolled by a positive feedback silicon controlled switch which serves as the latching mechanism. The structure of the latching driver is of an advanced integrated design employing a plurality of lateral complementary transistors in two isolation regions.
