    ACPL-227-50BE

    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 halfpitch phototransistor optocoupler that contains four lightemitting 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.
