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.
