Package Outline
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
base-collector capacitance of the input transistor.
The devices are packaged in an 8-pin DIP package
and also available in gullwing (400mil) and surface
mount lead forming.
Schematic
Note: Different bending options available. See package
