Recommended Operation
The HCPL-2503 optocoupler is specified for use in LSTTL-
to-LSTTL and TTL-to-LSTTL interfaces. The recommended

Electrical Specifications. The value given for I
based on the minimum CTR and the minimum I
worst case values for R
has ample design margin, allowing more than 20% for
CTR degradation even under these worst case condi-
tions. For additional information on CTR degradation
see Application Note 1002.
