128 Segment LCD Drivers
CMOS
The MC14LC5003/5004 are 128-segment, multiplexed-by-four LCD Driv-
ers. The two devices are functionally the same except for their data input
protocols. The MC14LC5003 uses a serial interface data input protocol. The
device 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 acknowl-
edge 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.
The MC14LC5003/MC14LC5004 drives the liquid-crystal displays in a mul-
tiplexed-by-four configuration. The device accepts data from a microproces-
sor or other serial data source to drive one segment per bit. The chip does
not have a decoder, allowing for the flexibility of formatting the segment data
externally.
Devices are independently addressable via a two-wire (or three-wire) com-
munication link which can be common with other peripheral devices.
The MC14LC5003/MC14LC5004 are low cost version of MC145003 and
MC145004 without cascading function.

* Maximum Ratings are those values beyond which damage to the device may occur. Func-
tional operation should be restricted to the limits in the Electrical Characteristics tables or
Pin Descriptions section.
This device contains protection circuitry
to guard against damage due to high static
voltages or electric fields. However, precau-
tions must be taken to avoid applications of
any voltage higher than maximum rated volt-
ages to this high-impedance circuit. This
device may be light sensitive. Caution
should be taken to avoid exposure of this
device to any light source during normal op-
eration. This device is not radiation protect-
ed.
