32-Channel Serial To Parallel Converter With High Voltage Push-Pull Outputs The HV5408PJ is a high-voltage, 8-bit serial-to-parallel converter manufactured by Supertex (now part of Microchip Technology).  

**Key HV Specifications:**  
- **Operating Voltage:** Up to **300V**  
- **Output Current:** **15mA per channel** (sink capability)  
- **Logic Supply Voltage (VDD):** **4.5V to 15V**  
- **High-Voltage Output Range:** **Up to 300V** (relative to COM pin)  
- **Serial Data Rate:** **Up to 10MHz**  
- **Package:** **20-pin PDIP**  

The device is designed for driving high-voltage loads such as piezoelectric actuators, vacuum fluorescent displays (VFDs), and electroluminescent displays.
