HCPL-4701-000E (BROADCOM LIMITED)

The HCPL-4701-000E is a 1-channel very low power consumption high gain Optocoupler. Each channel 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 photo-detector 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. This device is designed for use in CMOS, LSTTL and other low power applications. It is especially well suited for ISDN telephone interface and battery operated applications due to the low power consumption.
