CMOS IC
LC74788, 74788M, 74788JM
On-Screen Display Controller
Overview
The LC74788, LC74788M, and LC74788JM are on-
screen display controller CMOS ICs that display
characters and patterns on the TV screen under
microprocessor control. These ICs support 12 × 18 dot
characters and can display 12 lines by 24 characters of
text.
Features
• Display format: 24 characters by 12 rows (Up to 288
characters)
• Character format: 12 (horizontal) × 18 (vertical) dots
• Character sizes: Three sizes each in the horizontal and
vertical directions
• Characters in font: 128 (128 characters, one spacing
character, and one transparent spacing character)
• Initial display positions: 64 horizontal positions and 64
vertical positions
• Blinking: Specifiable in character units
• Blinking types: Two periods supported: About 1.0
second and about 0.5 second
• Blanking: Over the whole font (12 × 18 dots)
• Background color: 8 colors (internal synchronization
mode): 2fSC and 4fSC
• Line background color
— Can be set for 3 lines
— Line background color: 8 colors (internal
synchronization mode): 2fSC and 4fSC
• External control input: 8-bit serial input format
• On-chip sync separator circuit
• Video outputs - NTSC, PAL, PAL-N, PAL-M, NTSC
4.43, and PAL60 format composite video outputs
• Package
— 24-pin plastic DIP-24S (300 mil)
— 24-pin plastic MFP-24 (375 mil)
— 24-pin plastic MFP-24S (300 mil)

Video signal input to the internal sync separator circuit (Used as either the horizontal
synchronizing signal or the composite synchronizing signal input when the internal sync
separator circuit is not used.)
Internal sync separator circuit bias voltage monitor
Internal sync separator circuit composite synchronizing signal output. Can be switched to
function as a signal (high, low, or ST. pulse) output by the SEL0 and MOD0 setting.
Inputs the vertical synchronizing signal created by integrating the SEPOUT pin output signal.
An integration circuit must be connected to the SEPOUT pin. This pin must be tied to VDD1 if
unused. This pin can be switched to function as the frame signal input mode by setting SEL1
high. This is valid when CTL3 is set high. This input has hysteresis characteristics.
Background color phase adjustment. Connect a resistor between this pin and ground.
System reset input
A pull-up resistor is built in and the input has hysteresis characteristics.
Power supply (+5 V: digital system power supply)
Note: Both VDD1 pins must be connected to the power supply.
