Optocoupler Logic-Out Push-Pull DC-IN 1-CH 8-Pin PDIP

The TLP557 consists of a GaAlAs light emitting diode and an integrated photo detector. This unit is 8-lead DIP package. TLP557 is suitable for base driving circuit of power transistor module up to 20A. External resistor needs to connect between pin 6 and pin 7. This is for constant current driving.
