HCNW2601-300E

Logic Output Optoisolators Overview

The HCNW2601-300E is a high-speed logic output optocoupler manufactured by Broadcom Limited. It features a single channel with an open collector and Schottky-clamped output configuration, designed for robust signal isolation in noisy environments. The device supports data rates up to 10 MBd and provides a minimum common-mode transient immunity of 10 kV/µs. Electrical specifications include a maximum propagation delay of 100 ns and a typical forward voltage of 1.64 V at a maximum DC forward current of 20 mA. It operates within a supply voltage range of 4.5 V to 5.5 V and withstands an isolation voltage of 5000 Vrms. The component is housed in an 8-DIP package suitable for through-hole mounting.

• Industrial control systems and automation networks
• Power supply feedback loops and monitoring circuits
• Data acquisition systems with isolated input channels

Logic Output Optoisolators Procurement Notes

Verify that the specific suffix '-300E' corresponds to the surface-mount or specific packaging variant required, as standard HCNW2601 may differ in physical form factor. Confirm RoHS compliance status, as some variants in this family are non-compliant. Ensure the procurement source provides valid datasheets matching the 5000 Vrms isolation rating and 10 kV/µs CMTI specifications to avoid counterfeit or mislabeled components.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required alongside strong noise immunity. The open-collector output necessitates an external pull-up resistor; ensure the chosen resistor value aligns with the desired rise time and load capacitance. Compare against HCPL-2601 if leaded versions are preferred over the specific packaging of the -300E suffix. Consider the 50 mA output current limit when designing the load circuitry to prevent device damage.

Logic Output Optoisolators Part Context

The HCNW2601 belongs to Broadcom's HCNW series of high-speed optocouplers, which are engineered for demanding applications where speed and reliability are critical. This series typically offers superior common-mode transient immunity compared to standard logic optocouplers. The HCNW2601 specifically targets markets requiring fast data transfer rates while maintaining strict electrical isolation standards between input and output domains.
