Description

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.
