HCPL-4503

These diode-transistor optocouplers use an insulatinglayer between a LED and an integrated photodetector toprovide electrical insulation between input and output.Separate connections for the photodiode bias and output-transistorcollector increase the speed up to a hundredtimes that of a conventional phototransistor couplerby reducing the base-collector capacitance.These single channel optocouplers are available in8-Pin DIP, SO-8 and Widebody package configurations.The HCPL-4502/4503 and HCNW4502/4503 are designedfor high speed TTL/TTL applications. A standard 16 mA TTLsink current through the input LED will provide enoughoutput current for 1 TTL load and a 5.6 kO pull-up resistor.CTR for these devices is 19% minimum at IF=16mA.
