Description

The MSM6779 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 MSM6779 latches the 4-bit parallel display data sent from a microcontroller or a LCD controller to generate a LCD driving signal. This MSM6779 has a power-save function that sets all the drivers except one to the low supply current status (IDD SBY).

This driver's 3V-operation allows significant reduction in current consumption, suitable for battery-driving. The bias voltage to specify a drive level can be supplied externally. The MSM6779 can be used for various types of LCD panels.
