HCPL-263A-500E

Logic Output Optoisolators Overview

The HCPL-263A-500E is a high-speed logic output optocoupler manufactured by Broadcom Limited. It features two independent channels within an 8-pin surface-mount package, specifically designed for robust signal isolation in demanding electronic environments. The device supports data rates up to 10 MBd and provides an insulation voltage of 3750 Vrms. Key electrical parameters include a forward current of 10 mA, a typical rise time of 42 ns, and a fall time of 12 ns. It incorporates Schottky clamping on the open collector outputs to enhance switching speed and minimize storage delay times.

Logic Output Optoisolators Feature Summary

• Features Schottky-clamped open collector outputs to reduce storage delay times and improve switching performance.
• Provides uni-directional signal transmission with high common-mode transient immunity.
• Compatible with HCMOS, LSTTL, and TTL logic families for versatile interface applications.

Logic Output Optoisolators Applications

• High-speed data communication interfaces requiring galvanic isolation
• Industrial control systems utilizing PLCs and microcontrollers
• Power supply circuits needing feedback loop isolation

Logic Output Optoisolators Procurement Notes

Verify the specific suffix '500E' to confirm the tape-and-reel packaging format, as this differs from other variants like '000E'. Ensure compliance with RoHS directives and check for AEC-Q100 automotive qualification status if deploying in vehicle electronics. Cross-reference datasheet specifications against system requirements for voltage ratings and thermal limits before finalizing procurement orders.

Logic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is required at speeds up to 10 MBd. The Schottky-clamped architecture makes it suitable for applications where fast turn-off times are critical. Consider the SOIC-8 surface mount footprint for automated assembly processes. Evaluate the 3750 Vrms isolation rating against system safety standards to ensure adequate creepage and clearance distances are maintained.

Logic Output Optoisolators Part Context

This device belongs to the HCPL-263A series of high-speed optocouplers. It shares functional similarities with the HCPL-263A-000E but differs primarily in packaging configuration. The series is engineered to provide reliable isolation between low-voltage digital circuits and higher-voltage power stages, maintaining signal integrity across the isolation barrier.

Logic Output Optoisolators Replacement Considerations

The HCPL-263A-000E serves as a direct pin-compatible alternative, differing only in packaging type (through-hole versus surface-mount). Verify that any substitute maintains the same 10 MBd data rate and 3750 Vrms isolation voltage to ensure circuit compatibility without redesigning the isolation barrier.
