Description
The ACPL-824 is an AC-input dual channel full-pitch phototransistor optocoupler which contains four light emitting diode optically coupled to two separate phototransistor. It is packaged in a 8-pin DIP package.
Likewise, the ACPL-844 is an AC-input quad channel full pitch phototransistor optocoupler which contains eight light emitting diode optically coupled to four separate phototransistor. It is packaged in a 16-pin DIP package For both types, it is also available in wide-lead spacing option and lead bend SMD option with input-output isolation voltage at 5000 Vrms. Response time, tr, is typically 4 µs and CTR is 20% to 300%.

Features
• Current transfer ratio (CTR: min. 20% at IF = ±1mA, VCE = 5V)
• High input-output isolation voltage (VISO = 5,000VRMS)
• Response time (tr: typ. 4µs at VCE = 2V, IC = 2mA, RL= 100W)
• Compact dual-in-line package
• Safety and regulatory approvals
   - CSA
   - UL 1577
   - IEC/EN/DIN EN 60747-5-2
• Options available:
   – Leads with 0.4” (10.16 mm) spacing (W00)
