This high gain series coupler uses a Light Emitting Diode and an integrated high gain photodetector to provide extremely high current transfer ratio between input and output. Separate pins for the photodiode and output stage result in TTL compatible saturation voltages and high speed operation. Where desired VCC and VO terminals may be tied together to achieve convention photodarlington operation.A base access terminal allows a gain bandwidth adjustment to be made.
The HCPL-0701 is for use in CMOS, LSTTL, or other low power application. A 400% minimum current transfer ratio is guaranteed over 0 to 70 degrees C operating range for only 0.5 mA of LED current.
Selection for lower input current down to 250 mA is available upon request.
The HCPL-0701 is a surface mount device packaged in an industry standard SOIC-8 footprint. The SOIC-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.
