Description
The ILD621/ ILQ621 and ILD621GB/ ILQ621GB are
multi-channel phototransistor optocouplers that use
GaAs IRLED emitters and high gain NPN silicon phototransistors. These devices are constructed using
double molded insulation technology. This assembly
process offers a withstand test voltage of 7500 VDC.
The ILD621/ ILQ621GB is well suited for CMOS interfacing given the CTR
1.0 mA. High gain linear operation is guaranteed by a
minimum CTR
of 100 % at 5.0 mA. The ILD/Q621
