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
CEsat
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 circuits, where constant DC V
IO
voltages are
present.

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not
implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute maximum
ratings for extended periods of the time can adversely affect reliability.

Refer to reflow profile for soldering conditions for surface mounted devices (SMD). Refer to wave profile for soldering conditions for through
hole devices (DIP).
