Description

These devices are very low power consumption, high gain single and dual channel optocouplers. The HCPL-4701 represents the single channel 8-Pin DIP configuration and is pin compatible with the industry standard 6N139. The HCPL-4731 represents the dual channel 8-Pin DIP configuration and is pin compatible with the popular standard HCPL-2731. The HCPL-070A and HCPL-073A are the equivalent single and dual channel products in an SO-8 footprint. Each channel can be driven with an input current as low as 40 µA and has a typical current transfer ratio of 3500%.
