Abstract: AN OPTICALLY-COUPLED, integrated, high breakover voltage, 1 x 4 ( 2 wire/bidirectional) PXPN crosspoint array, for telephone speech paths, will be reported.The recent development of electrical triggering type solid-state crosspoints has spurred interest in their application for high performance telephone exchange networks'". But, it has bcen difficult to meet the demands for adequate tolerance of overvoltage and capability of isolating the speech path from the triggering circuit.The array t o be discussed fea…
