### **Specifications:**  
- **Channels:** 16  
- **Output Current:** Adjustable (up to 120 mA per channel)  
- **Supply Voltage (VCC):** 3 V to 5.5 V  
- **Logic Input Voltage:** 3 V to 5.5 V (TTL/CMOS compatible)  
- **Data Transfer Rate:** Up to 30 MHz  
- **Power Dissipation:** 1.5 W (max)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** HTSSOP-24, TSSOP-24  

### **Descriptions:**  
- The TLC5922 is designed for driving LEDs with constant current, ensuring uniform brightness.  
- It includes a shift register and latch for easy cascading in large LED matrix applications.  
- Each channel has an individually adjustable current setting via an external resistor.  
- Features thermal shutdown and open-load detection for protection.  

### **Features:**
