Overview
The LC74711 is a CMOS LSI for applications involving
microcomputer control of on-screen character and
graphics displays. Built-in character ROM supplies 128
alphanumerics and each character is generated in a 12
by 18 pixel format. The display is capable of supporting
a maximum of 288 characters within a 24 characters by
12 line array.
