MSM6779B Overview
The MSM6779B is a LCD dot matrix segment driver. Fabricated in CMOS technology, the device consists of 160-bit latches I and II, a 160-bit level shifter, and a 4-level driver. The MSM6779B latches the 4-bit parallel display data sent from a microcontroller or a LCD controller to generate a LCD driving signal.
