Description

The HCPL-181 contains a light emitting diode optically

coupled to a phototransistor. It is packaged in a 4-pin minifl at SMD package with a 2.0 mm profi le. The small dimension

of this product allows signifi cant space saving. The package

volume is 30% smaller than that of conventional DIP type.

Input-output isolation voltage is 3750 Vrms. Response

time, tr, is typically 4 μs and minimum CTR is 50% at input

current of 5 mA.
