Description

The 6N135, 6N136, EL4502 and EL4503 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 available in wide-lead

spacing and SMD option

Applications

•

Line receivers

•

Telecommunication equipments

•

Power transistor isolation in motor drives

•

Replacement for low speed phototransistor photo couplers

•

Feedback loop in switch-mode power supplies

•

Home appliances

•

High speed logic ground isolation
