1. Description

The ACPL-227-500E 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.

2. Features

    1. Current transfer ratio (CTR: 50% (min) at IF = 5 mA, VCE = 5V)

    2. High input-output isolation voltage (VISO = 3750VRMS)

    3. Non-saturated response time (tr: 2 μs (typ) at VCC = 10V, IC = 2 mA, RL= 100)

    4. SO package

    5. CMR 10 kV/μs (typical)

    6. Options available:

        - CTR Ranks 0, B, and C for ACPL-227 and Rank 0 only for ACPL-247

3. Applications

    1. I/O Interface for programmable controllers, computers

    2. Sequence controllers

    3. System appliances, measuring instruments

    4. Signal transmission between circuits of different potentials and impedances
