DESCRIPTION
The SFH636 is an optocoupler with a GaAlAs infrared
emitting diode, optically coupled to an integrated photodetector consisting of a photodiode and a high
speed transistor in a DIP-6 plastic package. The
device is functionally similar to 6N136 except there is
no base connection, and the electrical foot print is
different. Noise and dv/dt performance is enhanced
by not bringing out the base connection.
Signals can be transmitted between two electrically
separated circuits up to frequencies of 2 MHz. The
potential difference between the circuits to be coupled should not exceed the maximum permissible
reference voltages.
