Description
The CTM452 and CTM453 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 Mini-Flat package .
Applications
Line receivers
Telecommunication equipment
Feedback loop in switch-mode power supplies
Home appliances
High speed logic ground isolation
