HD66137T High-Voltage Durable 240-Channel Common Driver for Dot-Matrix STN LCD ADE-207-291(Z) Rev. 2 Aug. 03, 1999 Description The HD 66137T is a 240-channel common driver which drives a dot matrix STN LCD panel. By changing the mode, this can be applied to 240- and 200- and 160- channel output. Through the use of a 43-V highvoltage CMOS process technology, a high-voltage drive of +21.5 V and –21.5 V, centering on VM is possible. –21.5V generated from +21.5 V with built-in switching circuit and external capacity. Low logicdrive voltage (3 V) is used. This device is used together with the segment driver HD66130, HD66134ST or HD66136. Features • • • • • • • • Display duty: Up to 1/240 LCD drive voltage: 43 V max Built-in switching circuit (to generate –21.
