Description
The ACPL-227 is a DC-input dual-channel half-pitch
phototransistor optocoupler that contains two light-emitting
diodes optically coupled to two separate phototransistors. It is
packaged in an 8-pin SO package.
Likewise, the ACPL-247 is a DC-input quad-channel half-pitch
phototransistor optocoupler that 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
3750VRMS. Response time, tr, is 2 μs typically, while minimum
CTR is 50 percent at input current of 5 mA.
