Key Features
- 12×18 character array with 8 background colors enables rich on-screen menu overlays for CRT and early LCD monitors
- Dedicated monitor application targeting reduces external component count versus general-purpose video ICs
- 24-pin DIP package allows through-hole assembly and easy replacement in legacy monitor service applications
Applications
The STV9425 is used in CRT and early flat-panel computer monitor OSD circuits to generate menu text and graphic overlays for brightness, contrast, and geometry adjustment. Its 12×18 character matrix with 8-color background supports multilingual OSD menus without an external microcontroller handling the character rendering. Legacy monitor manufacturers and service centers use it as a drop-in replacement for STV9425-compatible OSD designs.

Frequently Asked Questions
What character matrix size does the STV9425 support and how does that affect menu readability on a CRT monitor?
The STV9425 supports a 12×18 pixel character array per glyph, producing legible menu text at standard VGA and SVGA resolutions. On a 15-inch CRT running 800×600 pixels, each 12×18 character occupies approximately 2 mm × 3 mm, sufficient for 3 to 4 lines of OSD text visible from a normal 50 cm viewing distance without an external character scaling circuit.
How many background colors does the STV9425 OSD IC provide and what does that enable for monitor menu design?
The STV9425 provides 8 background colors using 3-bit RGB encoding, allowing designers to use color-coded menu sections for different adjustment categories such as color settings, geometry, and input source selection. With 8 distinct colors available at no additional chip cost, OSD menus can highlight the active menu item in a contrasting color against a 7-color palette for improved usability versus single-color OSD implementations.
In a legacy CRT monitor repair scenario, what is the pin-compatible replacement option if STV9425 inventory is depleted?
When STV9425 stock is exhausted, engineers evaluate the STV9426 and similar ST OSD ICs that share the 24-pin DIP footprint and compatible I2C or parallel control interface, though firmware changes of 10 to 20 register writes may be required to remap character table addresses. The 24-pin DIP package with 2.54 mm pitch makes direct socketed substitution feasible without PCB modification during legacy monitor refurbishment projects.
