HCPL-263N-300E

Logic Output Optoisolators Overview

The HCPL-263N-300E is a dual-channel high-speed optocoupler manufactured by Broadcom Limited. It features an open collector output with Schottky clamping and supports a data rate of 10 MBd. The device provides 3750 Vrms isolation voltage and a minimum common mode transient immunity (CMTI) of 15 kV/µs. Electrical specifications include a typical rise time of 42 ns, a typical fall time of 12 ns, and a maximum forward current of 10 mA. The component operates within a temperature range of -40°C to +85°C and is housed in an 8-pin surface mount DIP package.

Logic Output Optoisolators Feature Summary

• High common mode transient immunity of 15 kV/µs for noise rejection
• Schottky-clamped open collector outputs for fast switching
• HCMOS compatible logic output interface

Logic Output Optoisolators Applications

• Industrial communication bus interfaces
• Data acquisition systems requiring galvanic isolation
• Signal transmission across noisy environments

Logic Output Optoisolators Procurement Notes

Verify the specific suffix '300E' to confirm the surface mount tube packaging variant. Ensure compatibility with HCMOS logic levels if used in digital circuits. Confirm RoHS compliance status through official datasheets or manufacturer declarations prior to integration into regulated assemblies.

Logic Output Optoisolators Selection Notes

Select this component when high-speed signal isolation is required alongside robust noise immunity. The 10 MBd data rate suits moderate-speed digital communications. Verify that the open collector output configuration aligns with the pull-up requirements of the receiving circuitry. Consider the 8-pin SMD footprint constraints during PCB layout design.

Logic Output Optoisolators Part Context

This part belongs to the HCPL-263N series of high-speed optocouplers. It shares functional similarities with other members like HCPL-2630 but differs in output type and speed characteristics. The series is designed for applications demanding reliable electrical isolation between low-voltage control circuits and higher-voltage power stages.

Logic Output Optoisolators Replacement Considerations

HCPL-2631-300E offers similar isolation and channel count but features different electrical parameters including a 10 mA forward current and 50 mA output current capability.
