HCPL-9000

Overview

The HCPL-9000 is a single-channel CMOS digital isolator utilizing symmetric magnetic coupling technology. It supports data rates up to 100 MBd with a maximum propagation delay of 15 ns and a typical pulse width distortion of 2 ns. The device operates on a supply voltage range of 3 V to 5.5 V, drawing 8 µA in standby and 3.3 mA during active operation. It provides an isolation voltage of 2500 Vrms and a minimum common-mode transient immunity of 15 kV/µs. The component features bidirectional polarity and is housed in an 8-pin DIP package.

Feature Summary

• Employs symmetric magnetic coupling barrier technology for high-speed signal transmission
• Provides excellent transient immunity with a minimum common-mode transient rejection capability
• Features low power consumption with distinct standby and active current specifications
• Includes logic output enable functionality for controlled signal directionality

Applications

• General-purpose electrical isolation between circuits operating at different voltage levels
• Industrial communication interfaces requiring high-speed data transfer
• Systems demanding robust protection against high common-mode transients

Procurement Notes

Verify the specific suffix code (e.g., -000E, -300E) to confirm the exact package type and lead-free status. Ensure the selected variant matches the required mounting style, such as through-hole DIP or surface-mount options. Confirm that the bidirectional channel configuration aligns with the circuit design requirements before finalizing the order.

Selection Notes

Select this component when a single-channel isolator with high-speed performance and strong transient immunity is required. It is suitable for applications needing compatibility with standard TTL/CMOS logic levels at both 3.3 V and 5 V supplies. Consider the bidirectional nature of the channel for flexible signal routing needs.

Part Context

This part belongs to the HCPL-90xx series of CMOS digital isolators from Broadcom Limited. The series includes various channel configurations, ranging from single to four channels, with options for unidirectional and bidirectional signal paths. These devices are designed for general-purpose isolation tasks requiring high reliability and fast switching speeds.

Replacement Considerations

Check for compatible variants within the HCPL-90xx family, such as HCPL-9030 for dual-channel unidirectional applications. Verify pinout compatibility if substituting with other single-channel isolators from different manufacturers.
