Description
Features
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.
• Current transfer ratio
(CTR: 50% (min) at IF = 5mA, VCC = 5V)
• High input-output isolation voltage
(VISO = 3,000VRMS)
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
• Non-saturated Response time
(tr: 2μs (typ) at VCC = 10V, IC = 2mA, RL= 100Ω)
