Description

The CTM109 series devices each consist of an

infrared emitting diode, optically coupled to a high

speed photo detector transistor. A separate

connection f or 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 a Mini-Flat package .

Applications

 Line receivers

 Telecommunication equipment

 Feedback loop in switch-mode power supplies

 Home appliances

 High speed logic ground isolation
