8-PIN WIDE BODY, HIGH-GAIN
OPTOCOUPLERS
CNW138 CNW139
DESCRIPTION
The CNW138 and CNW139 are high isolation voltage optocouplers, comprising an
infrared emitting AlGaAs diode, optically coupled to a high gain split Darlington
photodetector in an 8-pin wide body dual-in-line package (DIP).
FEATURES
• Wide body DIL encapsulation, with a pin distance of 10.16 mm
• Minimum clearance of 9.6 mm and minimum creepage of 10 mm
• High current transfer ratio
• Short propagation delay times
• TTL compatible
• Low saturation voltage
• High transient immunity
• Maximum permissible voltage of 8000 V (peak) and maximum
operating isolation voltage of 1000 V (RMS) in accordance with
VDE 00884
• UL recognized (File # E90700)
APPLICATIONS
• Line receivers
• Logic families ground isolation
• Low power systems
• Line voltage status indicator.
