CMOS LSI

LC7930N, 7930NW

LCD Drivers

Overview

The LC7930N, 7930NW are CMOS LSIs which incorporate

20-bit shift register, latch, and two sets of 20 LCD drivers.

They also have two switching pins: one of them (channel 2)

can be used as a scan-line driver (back plate) and the other

(channel 1) as a segment driver. They are optimal for LCD

interface with microcontroller (4 or 8 bits) or dot matrix

controller circuit incorporating character generator.
