... Liquid Crystal Display Description The HD66130T is a 320-channel segment driver for driving a dot-matrix STN liquid-crystal panel at a low voltage. The driver can also correspond to 240-channel output by switching mode. It operates at a low voltage: a liquid-crystal drive voltage and a logic drive voltage and is used together with common driver HD66131T or HD66135T ...
