ACPL-217
DC Input , Half-Pitch Phototransistor Optocoupler
Data Sheet
Description
The ACPL-217 is a DC-input single channel half-pitch
phototransistor optocoupler which contains a light
emitting diode optically coupled to a phototransistor. It is
packaged in a 4-pin SO package.
The input-output isolation voltage is rated at 3000 Vrms.
Response time, tr, is 2s typically, while minimum CTR is
50% at input current of 5 mA
