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.

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. The MC14LC5002 is the same as MC14LC5003 except for 72 segments. The three devices are functionally the same except for their data input protocols. The MC14LC5002/5003 use a serial interface data input protocol. The devices may be interfaced to the MC68HCXX product families using a minimal amount of software (see example). The MC14LC5004 has a IIC interface and has essentially the same protocol, except that the device sends an acknowledge bit back to the transmitter after each eight-bit byte is received. MC14LC5004 also has a “read mode”, whereby data sent to the device may be retrieved via the IIC bus.
