HCPL-0466

Logic Output Optoisolators Overview

The HCPL-0466 is a single-channel logic output optoisolator featuring an AlGaAs LED optically coupled to an integrated high-gain output stage. It provides 3750Vrms isolation voltage and supports data rates up to 1MBd with a common mode transient immunity of 15kV/µs. The device utilizes an open collector, Schottky-clamped output capable of handling a maximum continuous output current of 15mA. Key electrical parameters include a forward voltage of 1.8V, a reverse voltage rating of 5V, and a maximum input current of 25mA. The component is housed in an 8-SOIC surface-mount package.

Logic Output Optoisolators Feature Summary

• Integrates an AlGaAs LED with a high-gain output stage for efficient signal transmission
• Features Schottky clamping on the open collector output to prevent saturation and improve switching speed
• Provides robust galvanic isolation with high common mode transient immunity

Logic Output Optoisolators Applications

• Isolation between microcontroller units and power switching devices
• Signal transmission in industrial control systems requiring high noise immunity

Logic Output Optoisolators Procurement Notes

Verify the specific ordering suffix, such as #060 or -500E, as these indicate distinct packaging configurations. Note that certain variants may be listed as obsolete or discontinued by the manufacturer. Confirm RoHS compliance status and availability through authorized distributors before finalizing procurement plans.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required for gate driving applications. The Schottky-clamped output design ensures fast switching performance suitable for MHz-range data rates. Ensure the system voltage requirements align with the 30V output voltage limit and the 3750Vrms isolation barrier.

Logic Output Optoisolators Part Context

This part belongs to Broadcom's family of intelligent power module and gate drive interface optocouplers. It shares architectural similarities with the HCPL-4506 and HCPL-J456, though it specifically utilizes an AlGaAs LED rather than GaAsP. The series is designed for applications demanding reliable isolation in noisy electrical environments.
