HCPL-2503 optocoupler equivalent, high speed logic interface optocoupler.
* Data rates to 250 kb/s NRZ
* LSTTL compatible
* High common mode transient immunity:
> 1000 V/µs
* 3750 Vdc withstand test voltage
* Open col.
* High speed logic ground isolation
– LSTTL-to-LSTTL and TTL-to-LSTTL
* High voltage isolatio.
The HCPL-2503 optocoupler is specified for use in LSTTLto-LSTTL and TTL-to-LSTTL logic interfaces. A nominal 8 mA sink current through the input LED will provide enough output current for proper operation of 1 LSTTL gate under worst-case conditions w.
