ACPL-224 / ACPL-244
AC Input Multi-Channel Half-Pitch
Phototransistor Optocoupler
Data Sheet
Lead (Pb) Free
RoHS 6 fully
compliant
RoHS 6 fully compliant options available;
-xxxE denotes a lead-free product
Description
The ACPL-224 is an AC-input dual channel half-pitch pho-
totransistor optocoupler each of which contains 2 light
emitting diodes connected inversely parallel & optically
coupled to 2 separate phototransistors. It is packaged in
an 8-pin SO package.
Likewise, the ACPL-244 is an AC-input quad channel half-
pitch phototransistor optocoupler each of which contains
2 light emitting diodes connected inversely parallel &
optically coupled to 4 separate phototransistors. It is
packaged in a 16-pin SO package.
For both devices, the input-output isolation voltage is
rated at 3,000 Vrms. Response time, tr, is 2μs typically,
while minimum CTR is 20% at input current of ±1 mA.
