HCPL-9000-300E

Overview

The HCPL-9000-300E is a single-channel digital isolator from the Broadcom HCPL-9000 series, utilizing magnetic coupling technology for signal transmission. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 100 Mb/s. The device provides an isolation voltage of 2500 Vrms with a common-mode transient immunity of 15 kV/µs. Key timing parameters include a propagation delay of 15 ns, and rise/fall times of 4 ns. It functions bidirectionally in a DIP-8 Gull Wing package, with a power dissipation rating of 150 mW and an operating temperature range from -40°C to +100°C.

Feature Summary

• Utilizes magnetic coupling technology for high-speed digital signal isolation
• Features excellent common-mode transient immunity specifications
• Supports bidirectional signal transmission within a single channel

Applications

• General-purpose digital isolation in industrial systems
• Isolation interfaces for microcontrollers and DSPs
• Signal transfer across isolated boundaries in measurement equipment

Procurement Notes

Verify the specific suffix '300E' against the official Broadcom datasheet to confirm the tape-and-reel packaging configuration and RoHS compliance status. Ensure the component matches the DIP-8 Gull Wing package dimensions and electrical characteristics defined in the HCPL-9000 family documentation before procurement.

Selection Notes

Select this component when a single-channel solution with magnetic coupling is required for high-speed applications up to 100 Mb/s. Consider the 2500 Vrms isolation rating and 15 kV/µs CMTI for environments requiring robust noise immunity. Verify that the 3 V to 5.5 V supply range aligns with the system's logic levels and that the DIP-8 package fits the PCB layout constraints.

Part Context

The HCPL-9000-300E belongs to the HCPL-9000 series of CMOS digital isolators manufactured by Broadcom Limited. This series is designed to replace traditional optocouplers in applications demanding higher speed and better reliability. The product line emphasizes low power consumption and high transient immunity, making it suitable for modern digital communication interfaces.

Replacement Considerations

Consult the Broadcom HCPL-9000 family cross-reference guide for verified substitutes. Potential equivalents may include other single-channel magnetic isolators with similar 100 Mb/s speeds and DIP-8 packages, provided they meet the 2500 Vrms isolation and 15 kV/µs CMTI requirements.
