The MSM5299A is a dot matrix LCD segment driver LSI which is fabricated using CMOS low power metal gate technology. This LSI consists of an 80-bit bidirectional shift register, 80-bit latch, 80-bit level shifter and 80-bit 4-level driver. It receives the display data, which is transferred in 4-bit parallel from a microcomputer or LCD controller LSI such as MSM6255, then outputs the LCD driving waveform to the LCD.
