Overview

MOTOROLA SEMICONDUCTOR TECHNICAL DATA www.DataSheet4U.com 72-Segment / 128-Segment LCD Drivers CMOS The MC14LC5003/5004 are 128-segment, multiplexed-by-four LCD Drivers.

Key Features

  • ged into four consecutive blocks of 32 parallel data bits. A time-multiplex of the four backplane drivers is made (each backplane driver becoming active then inactive one after another) and, at the start of each backplane active period, the corresponding block of 32 bits is made available at the frontplane drivers. A high input to a plane driver turns the driver on, and a low input turns the driver off. Figure 4 shows the sequence of backplanes. Figure 5 shows the possible configurations of the f.
