MC141511AMOTOROLA
LCD Segment Driver
CMOS
The MC141511A is an LCD frontplane (segment) driver chip which includes a 656 x 8 display RAM. The MC68HC05L10 microcomputer is the
companion device which provides the backplane drive.
The MC68HC05L10, together with one MC141511A, may be used to
drive a 5248-pixel muxed-by-41 display or a 4096-pixel muxed-by-32 display. Larger displays may be driven by adding additional MC141511A.
The MC141511A is a low operating voltage version of MC141511. It is
pin to pin compatible to the MC141511.
See Application Note AN-HK-13A.

ELECTRICAL CHARACTERISTICS (Voltage Referenced to VSS, TA= 25˚C)
This device contains circuitry to protect the inputs
against damage due to high static voltages or electric fields; however, it is advised that normal precautions to be taken to avoid application of any voltage
higher than maximum rated voltages to this high
impedance circuit. For proper operation it is recommended that Vin and V
out
be constrained to the
range VSS < or = (Vin or V
out
) < or = VDD. Reliability
of operation is enhanced if unused input are connected to an appropriate logic voltage level (e.g.,
either VSS or VDD). Unused outputs must be left
open. This device may be light sensitive. Caution
should be taken to avoid exposure of this device to
any light source during normal operation. This
device is not radiation protected.
