Ordering number :EN4846A
CMOS IC
LC74761, 74761M
On-Screen Display LSI
Overview
The LC74761 and LC74761M are on-screen display
CMOS LSIs that superimpose text and low-level graphics
onto a TV screen (video signal) under microcontroller.
The display characters have a 12 by 18 dots structure, and
256 characters are provided.
Features
• Display structure: 12 lines by 24 characters (up to 288
characters)
• Maximum character display: Up to 288 characters
• Character configuration: 12 (W) by 18 (H) dots structure
• Number of characters: 256 characters (254 plus space 1
font and transparent space 1 font)
• 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,
