HCNW4506-500E

Logic Output Optoisolators Overview

The HCNW4506-500E is a high-speed logic output optocoupler from Broadcom Limited, housed in an 8-pin WDIP (Wide DIP) package. It features a single channel with DC input and an open-collector Schottky-clamped phototransistor output. Key electrical parameters include a maximum forward voltage of 1.85V, a typical rise/fall time of 5ns, and a maximum current transfer ratio of 90%. The device supports a maximum input current of 25mA and offers an isolation voltage of 5000Vrms. It operates within a temperature range of -40°C to 100°C and complies with UL, CSA, and IEC/EN/DIN EN 60747-5-2 standards.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix '500E' corresponds to the tape-and-reel packaging variant when ordering. Confirm that the required isolation voltage rating of 5000Vrms meets the safety regulations of the target application region. Ensure the 8-pin Wide DIP footprint matches the PCB design constraints. Cross-reference the manufacturer's latest datasheet for any updates on RoHS compliance status or recommended soldering profiles prior to procurement.

Logic Output Optoisolators Selection Notes

Select this component when high-speed signal transmission with robust noise immunity is required. The 15kV/µs CMTI rating makes it suitable for noisy environments such as motor drives. Compare against the HCPL-4506 series if lower isolation voltage (3750Vrms) is acceptable. Ensure the 5ns propagation delay aligns with the system timing requirements. Verify that the open-collector output type is compatible with the downstream logic level shifting needs.

Logic Output Optoisolators Part Context

This part belongs to the HCNW series of high-speed optocouplers from Broadcom Limited. It is distinct from the HCPL series, which typically offers lower isolation voltages. The HCNW series is designed for applications demanding faster response times and higher reliability compared to standard general-purpose optocouplers. It serves as a bridge between low-voltage control circuits and high-voltage power stages.

Logic Output Optoisolators Replacement Considerations

Check for direct substitutes within the HCNW family, such as HCNW4504-500E, noting differences in current transfer ratio and data rates. Verify pinout compatibility before substituting with other 8-pin DIP optocouplers. Ensure any replacement maintains the 5000Vrms isolation rating and 15kV/µs CMTI specification.
