HCPL-9031-300E

Digital Isolators Overview

The HCPL-9031-300E is a general-purpose digital isolator manufactured by Broadcom Limited. It features two independent channels with unidirectional signal transmission capability. The device utilizes Giant Magnetoresistive (GMR) technology for magnetic coupling isolation, providing a rated insulation voltage of 2500 Vrms. It supports high data rates up to 110 MBd with typical propagation delays of 15 ns and rise/fall times of 1 ns. The component operates within a supply voltage range of 3 V to 5.5 V and offers a common-mode transient immunity of 15 kV/µs. It is housed in an 8-SMD, Gull Wing surface-mount package.

Digital Isolators Procurement Notes

Verify the specific suffix '300E' confirms the 8-SMD Gull Wing surface-mount package configuration. Ensure compatibility with the required 3 V to 5.5 V supply voltage range. Confirm that the 2500 Vrms isolation rating meets the safety standards of the target application. Check for RoHS compliance status if restricted substances are a concern. Validate pinout alignment with existing PCB footprints before integration.

Digital Isolators Selection Notes

Select this component when high-speed digital isolation is required without the need for integrated isolated power supplies. The GMR technology offers superior performance compared to traditional optical couplers in terms of speed and reliability. Consider the 15 kV/µs CMTI rating for applications with significant electrical noise. Ensure the operating temperature range of -55°C to 125°C fits the environmental conditions. Compare against other HCPL-90xx series variants for channel count or package differences.
