HCPL-073A

Very Low Power Consumption High Gain Optocouplers

Currently Viewing:

This device is a very low power consumption high gain dual channel optocoupler. It is the equivalent dual channel product of the single channel HCPL-070A in an SO-8 footprint. Each channel can be driven with an input current as low as 40 mA 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. 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. A 700% minimum current transfer ratio is guaranteed from 0oC to 70oC operating temperature range at 40 mA of LED current and VCC >= 3 V.

The SO-8 does not require "through holes" in a PCB. This package occupies approximately one-third the footprint area of the standard dual-in-line package. The lead profile is designed to be compatible with standard surface mount processes.
