Overview
The LC74760 and LC74760M are on-screen display CMOS ICs that superimpose text and low-level graphics onto a TV screen (video signal) under microprocessor control. The display characters have a 12 by 18 dot structure, and 128 characters are provided. The display area consists of 12 lines of 24 characters each.

Features
• Display structure: 12 lines by 24 characters (up to 288 characters)
• Number of displayed characters: Up to 288 characters
• Character configuration: 12 (W) by 18 (H) dot structure
• Character sizes: Three sizes (normal, double, and triple sizes)
• Display starting positions: 64 horizontal and 64 vertical locations
• Reverse video function: Characters can be inverted on a per character basis.
• Flashing types: Two types with periods of 0.5 and 1.0 second on a per character basis (duty fixed at 50%)
• Background color: One of eight colors (when internal synchronization used)
• External control input: Serial data input in 8-bit units
• Built-in horizontal/vertical sync separation circuit, AFC circuit, and synchronization detector
• Video output: Composite video signal output in NTSC, PAL, PAL-M, PAL-N, PAL60, NTSC4.43, or SECAM format
