HCPL-0631-500E

Logic Output Optoisolators Overview

The HCPL-0631-500E is a high-speed, dual-channel logic output optocoupler manufactured by Broadcom Limited. It features an open collector output with Schottky clamping to minimize storage time and enhance switching speed. The device provides 3750 Vrms isolation voltage and supports data rates up to 10 MBd. Key electrical parameters include a forward current of 10 mA, a typical rise time of 24 ns, and a fall time of 10 ns. It operates within a temperature range of -40°C to +85°C and is housed in an 8-pin SOIC surface-mount package.

Logic Output Optoisolators Feature Summary

• Dual-channel architecture with open collector outputs for flexible logic interfacing
• Schottky clamping integrated to reduce storage time and improve switching performance
• High common-mode transient immunity (CMTI) rated at 10 kV/µs for noise resilience
• TTL-compatible input design simplifying integration with standard digital logic families

Logic Output Optoisolators Applications

• Industrial networking systems requiring galvanic isolation between diverse voltage levels
• Signal transmission across isolated ground planes in automated control equipment
• Data communication interfaces where high-speed signal integrity and noise immunity are critical

Logic Output Optoisolators Procurement Notes

Verify the specific suffix '500E' confirms RoHS compliance and lead-free status as per manufacturer specifications. Ensure the procurement source provides official datasheets matching the HCPL-0631-500E part number to confirm the 10 kV/µs CMTI rating, distinguishing it from lower-specification variants within the same family. Cross-reference the SOIC-8 package dimensions against your PCB footprint requirements prior to ordering.

Logic Output Optoisolators Selection Notes

Select this component when dual-channel isolation with high-speed TTL compatibility is required. The 10 kV/µs CMTI rating makes it suitable for noisy industrial environments compared to standard optocouplers. Consider the open collector output type for level shifting applications. Verify that the 3750 Vrms isolation voltage meets the safety requirements of the target application circuit.

Logic Output Optoisolators Part Context

This device belongs to the HCPL series of high-speed optocouplers designed for robust signal transmission. It shares architectural similarities with single-channel variants like the HCPL-0601-500E but offers dual-channel capability. The inclusion of Schottky clamping differentiates it from basic transistor-output optocouplers, providing faster turn-off times essential for high-baud-rate data links.
