ELM452 photocoupler equivalent, transistor photocoupler.
* High speed 1Mbit/s
* High isolation voltage between input and output (Viso=3750 Vrms )
* High CMR 15KV/us at VCM=1500V (ELM453)
* Guaranteed performance.
* Line receivers
* Field bus communication and control.
* Power transistor isolation in motor drives
* R.
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 .
