2. General
The TLP3350 is a photorelay in a 4-pin USOP that consists of a photo
MOSFET optically coupled with an infrared LED. The TLP3350 features low output capacitance, COFF, and thus fast on/off switching of a high-frequency signal, making it ideal for switching applications in high-speed testers.
