HCPL-073A-000E (BROADCOM LIMITED)

The HCPL-073A-000E is a 2-channel 8-pin very low power consumption High Gain Optocoupler can be driven with an input current as low as 40µA and has a typical current transfer ratio of 3500%. This high gain coupler uses 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. This device is designed for use in CMOS, LSTTL or other low power applications. It is 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 to 70°C operating temperature range at 40µA of LED current and VCC >= 3V. It is suitable for ISDN telephone interface, low input current line receiver, telephone ring detector and portable system I/O interface.
