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

Tin-plating
