HCPL-4701-320E

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. Each channel can be driven with an input current as low as 40 µA and has a typical current transfer ratio of 3500%. These high gain couplers use an AlGaAs LED and an integrated high gain photodetector to provide an extremely high current transfer ratio between input and output. Separate pins for the photodiode and output stage results in TTL compatible saturation voltages and high speed operation. Where desired, the VCC and VO terminals may be tied together to achieve conventional Darlington operation (single channel package only). These devices are designed for use in CMOS, LSTTL or other low power applications. They are especially well suited for ISDN telephone interface and battery operated applications due to the low power consumption. A 700% minimum current transfer ratio is guaranteed from 0°C to 70°C operating temperature range at 40 µA of LED current and VCC = 3 V.
