The output makes the OPF520 compatible with TTL and CMOS logic. The receiver is designed to operate from a single +5 V supply. It is essential that a bypass capacitor be connected from VCC to Common of the receiver. This component is susceptible to damage from electrostatic discharge (ESD). Normal static precautions should be taken in handling and assembly of this component to prevent ESD damage or degradation. Optek Technology, Inc. 1215 W.
