HCPL-0900

Overview

The HCPL-0900 is a general-purpose digital isolator manufactured by Broadcom Limited. It features one channel of unidirectional data transmission with a data rate of 100 Mb/s. The device provides an insulation voltage of 2500 Vrms using magnetic coupling technology. It operates within a supply voltage range of 3 V to 5.5 V and supports a propagation delay of 15 ns. The component is housed in an 8-SOIC package and functions across a temperature range of -40°C to +100°C.

Feature Summary

• Provides galvanic isolation via magnetic coupling for signal integrity
• Supports high-speed data transmission at 100 Mb/s rates
• Features unidirectional channel configuration for simple interface applications

Applications

• ATM Forum UNI SONET compliant interfaces
• General purpose digital isolation in industrial systems
• Signal isolation between microcontrollers and peripheral devices

Procurement Notes

Verify the specific suffix code (e.g., 000E, 500) against the manufacturer's current product status, as availability varies by variant. Confirm RoHS compliance details directly from the official datasheet, as some listings indicate non-compliance while others suggest compliance. Ensure the ordering part number matches the required packaging and lead-free specifications for your assembly process.

Selection Notes

Select this component when a single-channel, unidirectional isolator is required for moderate-speed digital signals. The 2500 Vrms isolation rating suits standard low-voltage logic separation tasks. Consider the 8-SOIC footprint for PCB layout constraints. Verify that the 100 Mb/s data rate meets the system timing requirements before finalizing the design.

Part Context

This device belongs to the HCPL series of digital isolators from Broadcom Limited. It utilizes magnetic coupling technology rather than optical or capacitive methods to transmit signals across isolation barriers. The series is designed for robust performance in noisy environments where electrical isolation is critical for protecting sensitive control circuitry.
