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 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.
