ILQ621 (VISHAY)

The ILQ621 is a 4-channel 16-pin Phototransistor Output Optocoupler uses GaAs IRLED emitters and high gain NPN silicon phototransistors. This device is constructed using double moulded insulation technology. This assembly process offers a withstand test voltage of 7500VDC. The ILQ621 is well suited for CMOS interfacing given the CTRCEsat of 30% minimum at IF of 1mA. High gain linear operation is guaranteed by a minimum CTRCE of 100% at 5mA. It has a guaranteed CTRCE 50% minimum at 5mA. The transparent ion shield insures stable DC gain in applications such as power supply feedback circuits, where constant DC VIO voltages are present.
