Description
The CTW135, CTW136, CTW4502, and CTW4503
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 device is packaged in an 8-pin wide body DIP
and also available in surface mount option.
Applications
• Line receivers
• Telecommunication equipment
• High speed logic ground isolation
• Feedback loop in switch-mode power supplies
• Home appliances
