Description
The ELM452 and ELM453 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 industry standard 5pin SOP
packages and are suitable for surface mounting.
Applications
Line receivers
Field bus communication and control.
Power transistor isolation in motor drives
Replacement for low speed phototransistor photo couplers
High speed logic ground isolation
Analog signal ground isolation
