HCPL-263N#320

Logic Output Optoisolators Overview

The HCPL-263N#320 is a high-speed logic output optoisolator featuring two independent channels within an 8-pin gull-wing surface mount package. It provides 5000 Vrms isolation voltage and supports data rates up to 10 Mb/s. The device utilizes an open collector output with Schottky clamping for fast switching, characterized by a rise time of 42 ns and fall time of 12 ns. It operates with a forward current of 10 mA and a forward voltage of 1.6 V. The unit withstands a reverse voltage of 5 V and offers common mode transient immunity of 15 kV/µs.

Logic Output Optoisolators Feature Summary

• Integrates GaAsP LED with high-gain photodetector for efficient signal transmission
• Features Schottky-clamped open collector outputs to minimize storage time and enhance speed
• Provides robust electrical isolation suitable for noisy industrial environments

Logic Output Optoisolators Applications

• High-speed data communication interfaces requiring galvanic isolation
• Industrial control systems with isolated I/O channels
• Power supply feedback loops for voltage regulation

Logic Output Optoisolators Procurement Notes

Verify the specific suffix #320 confirms the gull-wing surface mount package variant rather than the through-hole PDIP version. Confirm RoHS compliance status as historical records may vary. Ensure the supplier source is authorized to guarantee component authenticity and traceability for critical isolation applications.

Logic Output Optoisolators Selection Notes

Select this component when 5000 Vrms isolation is required alongside 10 Mb/s data throughput. The open collector output necessitates external pull-up resistors; ensure circuit design accommodates this topology. Compare against HCPL-2631 if higher output current capability or different insulation ratings are needed for the specific application constraints.

Logic Output Optoisolators Part Context

This part belongs to the HCPL-263x family of high-speed optocouplers from Broadcom Limited. It shares functional similarities with the HCPL-2630 and HCPL-2631 but differs in packaging and specific electrical parameters such as isolation voltage and output drive characteristics. It serves as a bridge between low-voltage logic circuits and high-voltage domains.

Logic Output Optoisolators Replacement Considerations

HCPL-2631#320 offers similar functionality but with 5000 Vrms isolation and 50 mA output current. HCPL-2630#320 provides comparable speed but may differ in insulation voltage ratings. Verify pinout compatibility and thermal performance before substitution.
