HCPL-1931

Logic Output Optoisolators Overview

The HCPL-1931 is a high-reliability, dual-channel optocoupler featuring hermetically sealed construction in a 16-pin ceramic DIP package. It operates with a data rate of 10 Mb/s and provides 1500 Vdc isolation voltage. The device utilizes open collector outputs with Schottky clamping, supporting a maximum output current of 25 mA per channel. Electrical characteristics include a forward current of 10 mA, typical rise and fall times of 30 ns and 24 ns respectively, and a propagation delay of up to 100 ns. It functions within a temperature range of -55°C to +125°C.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., #100) against official Broadcom documentation to confirm package type and compliance status. Ensure the procurement source provides valid traceability for hermetically sealed components. Confirm RoHS status through official datasheets as historical variants may differ. Validate supplier authorization to prevent counterfeit high-reliability parts.

Logic Output Optoisolators Selection Notes

Select this component when hermetic sealing and high common-mode rejection are critical requirements. The 10 Mb/s data rate suits moderate-speed digital isolation needs. Verify that the 16-pin DIP footprint fits the design constraints. Consider the operating temperature range if deployed in extreme environments.

Logic Output Optoisolators Part Context

This part belongs to the HCPL-193X series of dual-channel optocouplers manufactured by Broadcom Limited. These devices are designed for applications demanding high reliability and noise immunity. The series typically features robust isolation barriers suitable for harsh industrial environments.

Logic Output Optoisolators Replacement Considerations

Check for direct pin-compatible substitutes within the HCPL-193X family. Verify electrical parameters such as CMTI and propagation delay before substituting with other high-speed optocouplers.
