Description
The ACPL-214 is an AC-input single channel half-pitch phototransistor optocoupler which contains 2 light emitting diodes connected inversely parallel & 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
20% at input current of 1 mA
