HCPL-2212

Logic Output Optoisolators Overview

The HCPL-2212 is a high-speed logic output optocoupler manufactured by Broadcom Limited. It features a single channel with a data rate of 5 MBd and an isolation voltage of 3750 Vrms. The device utilizes a GaAsP LED input and provides push-pull or open collector outputs, depending on the specific suffix variant. Key electrical parameters include a maximum propagation delay of 300 ns, a common mode transient immunity of up to 10 kV/µs, and a forward current rating of 5 mA. It operates within a temperature range of -40°C to 85°C.

Logic Output Optoisolators Feature Summary

• High common mode transient immunity for noise-resistant signal transmission
• CMOS compatible logic interface for direct integration with digital circuits
• Single-channel design with fast switching speed capabilities

Logic Output Optoisolators Applications

• Industrial communication systems requiring galvanic isolation
• Microprocessor system interfacing
• Signal isolation in noisy electrical environments

Logic Output Optoisolators Procurement Notes

Verify the exact ordering suffix (e.g., #500, -000E) as it determines the specific output configuration and packaging type. Confirm RoHS compliance status for the specific revision. Check availability as some variants may be discontinued or subject to supply constraints. Ensure the selected part matches the required isolation voltage and data rate specifications for the target application.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required between CMOS or TTL logic circuits. Consider the specific output stage (push-pull vs. open collector) based on the load requirements of the receiving circuit. Verify that the operating temperature range meets the environmental conditions of the deployment site. Ensure the isolation voltage rating exceeds the system's peak transient voltages.

Logic Output Optoisolators Part Context

The HCPL-2212 belongs to the Broadcom HCPL-22XX family of optically coupled logic gates. This series integrates a GaAsP light-emitting diode with a dedicated output logic circuit to provide high-speed signal transfer. The family is designed for applications demanding reliable isolation between low-voltage digital logic and higher-voltage or noisy domains.

Logic Output Optoisolators Replacement Considerations

Check datasheets for HCPL-2211 or HCPL-2202 if dual-channel functionality is needed instead of single-channel. Verify pinout compatibility before substituting with other high-speed optocouplers from different manufacturers.
