HCNW2211

Logic Output Optoisolators Overview

The HCNW2211 is a high-speed logic gate optocoupler featuring an AlGaAs LED and totem pole output stages. It supports data rates up to 5 MBd with typical rise and fall times of 30 ns and 7 ns, respectively. The device provides 5000 Vrms isolation voltage and 10 kV/µs common-mode transient immunity. Operating supply voltage ranges from 4.5 V to 20 V, with a maximum forward current of 10 mA. Propagation delays are typically 160 ns (low-to-high) and 180 ns (high-to-low).

Logic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., -000E, -300E, -500E) to ensure correct package type and mounting style, as these variants differ significantly in physical form factor despite sharing the core HCNW2211 designation. Confirm RoHS compliance status and check for lead-free specifications if required by project standards. Ensure the selected variant matches the intended PCB layout constraints regarding through-hole versus surface-mount requirements.

Logic Output Optoisolators Selection Notes

Select this component when high-speed data transfer exceeding standard optocoupler capabilities is necessary. The wide operating voltage range of 4.5 V to 20 V offers flexibility in power supply design. Consider the totem pole output structure for direct logic interface compatibility without additional pull-up resistors. Evaluate the 10 kV/µs CMTI rating against the electromagnetic interference levels present in the target application environment to ensure reliable signal integrity.

Logic Output Optoisolators Part Context

The HCNW2211 belongs to Broadcom's HCNW series of very high common-mode rejection logic gate optocouplers. This family is designed to replace slower or less robust isolation components in modern high-speed digital circuits. The device utilizes advanced AlGaAs technology to achieve superior speed and reliability compared to traditional GaAs-based optocouplers, making it suitable for demanding industrial and commercial applications.

Logic Output Optoisolators Replacement Considerations

Direct substitutes include HCPL-2202 and HCPL-2211 from the same manufacturer family. Verify pinout compatibility and electrical parameter equivalence before substitution. Cross-reference datasheets to confirm that propagation delay and isolation voltage ratings meet or exceed original design specifications.
