Description
The ILD621/ ILQ621 and ILD621GB/ ILQ621GB are
multi-channel phototransistor optocouplers that use
GaAs IRLED emitters and high gain NPN silicon pho-
totransistors. 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 inter-
facing given the CTR
CE sat
of 30 % minimum at I
F
of
1.0 mA. High gain linear operation is guaranteed by a
minimum CTR
CE
of 100 % at 5.0 mA. The ILD/Q621
has a guaranteed CTR
CE
50 % minimum at 5.0 mA.
The TRansparent IOn Shield insures stable DC gain
in applications such as power supply feedback cir-
cuits, where constant DC V
IO
voltages are present.
