HCNW4502-000E

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 Features These diode-transistor opto­ coup­ lers 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. • 15 kV/µs minimum common mode transient immunity at VCM = 1500 V • High speed: 1 Mb/s • TTL compatible • Available in 8-Pin DIP, SO-8, widebody packages • Open collector output • Guaranteed performance from temperature: 0°C to 70°C • Safety approval UL Recognized – 3750 Vrms for 1 minute (5000 Vrms for 1 minute for HCNW and Option 020 devices) per UL1577 CSA Approved IEC/EN/DIN EN 60747-5-5 Approved   – VIORM = 630 V peak for HCPL-4503#060   – VIORM = 1414 V peak for HCNW devices • Dual channel version available (4534/0534) • MIL-PRF-38534 hermetic version available (55XX/65XX/4N55) These single channel optocoup­ lers 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.
