High Speed Optocoupler, 1 MBd, Transistor Output

DESCRIPTION The SFH636 is an optocoupler with a GaAlAs infrared emitting diode, optically coupled to an integrated photo detector consisting of a photo diode and a high speed transistor in a low pinout DIP-6 package. The device is functionally similar to 6N136 except there is no base connect
