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.
