A 0.1 F bypass capacitor connected between pins 8 and 5 is recommended. CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to prevent damage and/or degradation which may be induced by ESD.Description These devices are very low power consumption, high These devices are designed for use in CMOS, LSTTL gain single and dual channel optocouplers. The or other low power applications. They are especially HCPL-4701 represents the single channel 8-Pin DIP well suited for ISDN telephone interface and battery configuration and is pin compatible with the industry operated applications due to the low power standard 6N139. The HCPL-4731 represents the dual consumption. A 700% minimum current transfer ratio channel 8-Pin DIP configuration and is pin is guaranteed from 0C to 70C operating temperature compatible with the popular standard HCPL-2731. range at 40 A of LED current and V 3V. CC The HCPL-070A and HCPL-073A are the equivalent single and dual channel products in an SO-8 footprint. The SO-8 does not require through holes in a PCB. Each channel can be driven with an input current as This package occupies approximately one-third the low as 40 A and has a typical current transfer ratio of footprint area of the standard dual-in-line package. 3500%. The lead profile is designed to be compatible with standard surface mount processes. 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 V and V terminals may be tied together to achieve CC O conventional Darlington operation (single channel package only).
