Description
The HCPL-354 contains a phototransistor, optically coupled to two light emitting diodes connected inverse parallel. It can operate directly by AC input current. It is packaged in a 4-pin mini-flat SMD package with a 2.0 mm profile. The small dimension of this product allows significant 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 20% at input current of ±1 mA.
