Description
These diode-transistor optocouplers use an insulating layer between a LED and an integrated photodetector to provide electrical insulation between input and output. Separate connections for the photodiode bias and output transistor collector increase the speed up to a hundred times that of a conventional phototransistor coupler by reducing the base collector capacitance.

Features
• 3.3V/5V Dual Supply Voltages
• Low power consumption
• High speed: 1 Mb/s
• LVTTL/LVCMOS compatible
• Available in 8-pin DIP, SO-8
• Open collector output
• Guaranteed performance from temperature: 0˚C to +70˚C
• Safety approval, UL, CSA, IEC/EN/DIN EN 60747-5-2

Applications
• High voltage insulation
• Video signal isolation
• Power translator isolation in motor drives
• Line receivers
• Feedback element in switched mode power supplies
• High speed logic ground isolation – LVTTL/LVCMOS
• Replaces pulse transformers
• Replaces slow phototransistor isolators
