Overview
The LC74721 and LC74721M are CMOS, video display
controllers for superimposing text and low-level graphics
onto an NTSC or PAL-M compatible television receiver.
Up to 240, 8
× 8-pixel characters can be displayed under
microprocessor control on a 24-character by 10-line dis-
play.
The LC74721 and LC74721M feature selectable pixel width
and height, and 64 vertical and 64 horizontal display start
positions. It also features a flashing enable bit for each char-
acter position.
The LC74721 and LC74721M operate from a 5V supply.
The LC74721 is available in 24-pin DIPs, and the
LC74721M, in 24-pin MFPs.
