Description and Introduction

On-screen Video Display Controller for NTSC or PAL-M The LC7472 is a CMOS LSI (Large Scale Integration) IC designed for video signal processing, particularly in TV applications. Below are its specifications, descriptions, and features based on available information:

### **Manufacturer:**  
- Sanyo (now part of ON Semiconductor or other successor entities due to corporate changes).

### **Key Specifications:**  
- **Function:** Video signal processor for TV systems.  
- **Process Technology:** CMOS.  
- **Package:** Likely a DIP (Dual In-line Package) or SOP (Small Outline Package), though exact package details may vary.  
- **Operating Voltage:** Typically 5V (confirm datasheet for exact range).  
- **Applications:** Used in CRT-based TVs for sync separation, deflection control, and OSD (On-Screen Display) signal generation.  

### **Features:**  
1. **Sync Separation:** Extracts horizontal and vertical sync signals from composite video.  
2. **Deflection Control:** Generates signals for CRT deflection circuits.  
3. **OSD Support:** On-screen display functionality for text/graphics overlay.  
4. **Low Power Consumption:** Due to CMOS design.  
5. **Integrated Functionality:** Combines multiple video processing functions into one chip.  

### **Descriptions:**  
- The LC7472 was commonly used in analog TV systems to manage video synchronization and display control.  
- It interfaces with other components like microcontrollers, deflection coils, and video amplifiers.  

For exact pinouts, electrical characteristics, or application circuits, refer to the official datasheet from the manufacturer.
