HCPL-0453

HCNW4502/3 HCPL-0452/0453/4502/4503 Single Channel, High Speed Optocouplers Data Sheet Lead (Pb) Free RoHS 6 fully compliant RoHS 6 fully compliant options available; -xxxE denotes a lead-free product Description These diode-transistor optoc­ oup­lers 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. These single channel optocoup­lers are available in 8-Pin DIP­, SO-8 and Widebody package configurations. The HCPL-4502/4503 and HCNW4502/4503 are designed for high speed TTL/TTL applications. A standard 16 mA TTL sink current through the input LED will provide enough output current for 1 TTL load and a 5.6 kΩ pull-up resistor. CTR for these devices is 19% minimum at IF = 16 mA.
