HCPL-4200 Datasheet PDF - HP => Agilent Technologies

Description
The HCPL-4200 optocoupler is designed to operate as a receiver in equipment using the 20 mA Current Loop. 20 mA current loop systems conventionally signal a logic high state by transmitting 20 mA of loop current (MARK), and signal a logic low state by allowing no more than a few milliamperes of loop current
(SPACE).

FEATUREs
• Data Output Compatible with LSTTL, TTL and CMOS
• 20 K Baud Data Rate at 1400 Metres Line Length
• Guaranteed Performance over Temperature (0°C to 70°C)
• Guaranteed On and Off Thresholds
