DESCRIPTION
The ILD/Q621 and ILD/Q621GB are multi-channel phototransistor optocou- plers that use GaAs IRLED emitters and high gain NPN silicon phototransis- tors. These devices are constructed using over/under leadframe optical coupling and double molded insulation technology. This assembly process offers a withstand test voltage of 7500 VDC. The ILD/Q621GB is well suited for CMOS interfacing given the CTR CEsat of 30% minimum at I F of 1 mA. High gain linear operation is guaranteed by a minimum CTR CE of 100% at 5 mA. The ILD/Q621 has a guaranteed CTR CE of 50% minimum at 5 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.
