onsemi, FOD819 AC Input Phototransistor Output Optocoupler, Through Hole, 4-Pin DIP

The FOD819 consists of a gallium arsenide (GaAs) infra-red emitting diode, driving a high speed photo detector with integrated base-to-emitter resistor, RBE, in a 4-pin dual-in-line package. It is designed to be an improved replacement to the popular FOD817 Series when higher speed performance is required in isolated data signal transmission.

High Speed Performance ∼ 30kHz
Current Transfer Ratio: 100% to 600%
Minimum BVCEO of 80V Guaranteed
Applications
Digital Logic Inputs
Microprocessor Inputs
Power Supply Monitor
Twisted Pair Line Receiver
Telephone Line Receiver
