HCPL-0931

Overview

The HCPL-0931 is a general-purpose digital isolator featuring two independent channels in an 8-SOIC package. It operates at data rates up to 110 MBd with a common-mode transient immunity of 15 kV/µs. The device provides 2500 Vrms isolation voltage and functions within a temperature range of -40°C to +100°C. Key electrical parameters include a propagation delay of 15 ns, operating supply current of 1.5 mA, and bidirectional configuration for full-duplex communication.

Feature Summary

• Provides high-speed signal transmission with 110 MBd data rate capability
• Features robust electromagnetic noise rejection via 15 kV/µs common-mode transient immunity
• Supports bidirectional data flow for efficient full-duplex system integration

Applications

• Industrial automation control systems
