Description 

The CTS452 and CTS453 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 a SDIP-6 package . 

Applications 

• Line receivers 

• Telecommunication equipment 

• Feedback loop in switch-mode power supplies 

• Home appliances 

• High speed logic ground isolation
