ACPL-227 / ACPL-247
DC Input Multi-Channel Half-Pitch
Phototransistor Optocoupler
Data Sheet
Description
The ACPL-227 is a DC-input dual channel half-pitch
phototransistor optocoupler which contains two light
emitting diodes optically coupled to two separate photo-
transistors. It is packaged in an 8-pin SO package.
Likewise, the ACPL-247 is a DC-input quad channel half-
pitch phototransistor optocoupler which contains four
light emitting diodes optically coupled to four separate
phototransistors. It is packaged in a 16-pin SO package.
For both devices, the input-output isolation voltage is
rated at 3,000 Vrms. Response time, tr, is 2s typically,
while minimum CTR is 50% at input current of 5 mA.
