GENERAL DESCRIPTION
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. This MSM6779B has a power-save function that sets all the drivers except
one to the low supply current status (I_DD 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
MSM6779B can be used for various types of LCD panels.
FEATURES
