Description
The ACPL-217 is a DC-input single channel half-pitch phototransistor optocoupler which contains a light emitting diode optically coupled to a phototransistor. It is packaged in a 4-pin SO package. The input-output isolation voltage is rated at 3000 Vrms. Response time, tr, is 2μs typically, while minimum CTR is 50% at input current of 5 mA

Features
• Current transfer ratio (CTR: 50% (min) at IF = 5mA, VCC = 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, A, B, C & D

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