6N135, 6N136, CT4502, CT4503
1Mbit/s High Speed Phototransistor Optocoupler
Description
The 6N135, 6N136, CT4502 and CT4503 devices
each consist of an infrared emitting diode, optically
coupled to a high speed photo detector transistor. A
separate connection for the photodiode bias and
output-transistor collector increase the speed by
several orders of magnitude over conventional
phototransistor
couplers
by
reducing
the
