Description

These high gain series couplers use a Light Emitting Diode and an integrated high gain photodetec tor 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 the VCC and VO terminals may be tied together to achieve conven tional photodarlington operation. A base access terminal allows a gain bandwidth adjustment to be made

Features

● High current transfer ratio – 2000 typical (4500 typical for HCNW139/138)
