ILQ621

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 CTRCEsat of 30 % minimum at IF of 1.0 mA. High
gain linear operation is guaranteed by a minimum CTRCE of
100 % at 5.0 mA. The ILD/Q621 has a guaranteed CTRCE
50 % minimum at 5.0 mA. The transparent ion shield insures
stable DC gain in applications such as power supply
feedback circuits, where constant DC VIO voltages are
present.
