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.

Features
• Current transfer ratio (CTR: 50% (min) at IF = 5mA, VCE = 5V)
• High input-output isolation voltage (VISO = 3,000VRMS)
• Non-saturated Response time (tr: 2μs (typ) at VCC = 10V, IC = 2mA, RL= 100Ω)
• SO package
• CMR 10kV/μs (typical)
• Safety and regulatory approvals
    - cUL
    - IEC/EN/DIN EN 60747-5-2
• Options available:
    – CTR Ranks 0, B & C for ACPL-227 and Rank 0 only for ACPL-247

Applications
• I/O Interface for Programmable controllers, computers.
• Sequence controllers
• System appliances, measuring instruments
• Signal transmission between circuits of different potentials and impedances.
