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 photo
transistor 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
