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 (IDD SBY).

FEATURES

• Logic supply voltage : 2.7 V to 5.5 V

• LCD drive voltage : A wide range from 14 V to 28 V

• Applicable LCD duty : 1/64 to 1/256

• The bias voltage can be supplied externally.

• LCD outputs : 160

• A power-save function to reduce power consumption in a large-screen LCD panel.

• A 4-bit parallel data transfer to reduces its transfer speed to 1/4 of conventional serial transfer, providing low power consumption.

• Data transfer clock frequency : 6.5 MHz

• 35mm-wide-film TCP
