PRECAUTIONS FOR DESIGN
The AC input compatible optocoupler is identical to the conventional optocoupler except for the presence of two LEDs connected
in reverse parallel in the input circuit. Therefore, the circuit configuration can be designed as conventionally. The difference is
that there are two types of current transfer ratios (CRT) because two LEDs are connected in the input circuit. The two CTRs are
not necessarily the same, owing to the differences in light emission and coupling efficiencies of LEDs. Consequently, this causes
deviation in output signal level. The differences are rated under the item of the current efficiency ratio (CTR
1
/CTR
2
) for electric
characteristics.
