HCPL-4200

Overview

The HCPL-4200 is a logic output optocoupler designed as an isolated receiver for simplex point-to-point 20 mA current loop applications. It features one channel with a voltage isolation rating of 3750Vrms. The device supports a maximum baud rate of 20 KBps and operates within a typical fall time of 0.015μs. It is available in an 8-pin PDIP package and functions as a DC input component.

Feature Summary

• Designed specifically for use as an isolated receiver in equipment utilizing the 20 mA current loop standard.
• Provides electrical isolation to enable diverse voltage levels to operate together in industrial networking systems.

Applications

• Simplex point-to-point 20 mA current loop communication
• Industrial networking systems requiring circuit isolation

Procurement Notes

Verify the specific ordering suffix, such as -000E, to confirm package type and compliance standards like UL 1577 or CSA. Confirm active status and lead times directly with authorized distributors. Ensure the selected variant matches the required isolation voltage and operating temperature range for the target environment.

Selection Notes

Select this component when a dedicated receiver is needed for 20 mA current loop interfaces. It pairs with transmitters like the HCPL-4100 for complete link solutions. Consider the 3750Vrms isolation barrier for noise immunity in high-voltage industrial environments where galvanic separation is critical.

Part Context

Broadcom Limited manufactures the HCPL-4200 as part of its semiconductor portfolio serving industrial markets.
