HCPL-2212-300E

Logic Output Optoisolators Overview

The HCPL-2212-300E is a single-channel high-speed logic output optocoupler from the Broadcom HCPL series. It features a GaAsP infrared LED coupled to a push-pull totem pole output stage, enabling data rates up to 5 MBd. Key electrical parameters include a typical propagation delay of 30 ns, rise and fall times of 30 ns and 7 ns respectively, and an isolation voltage of 3750 Vrms. The device operates with a maximum forward current of 5 mA and supports collector-emitter voltages up to 20V.

Logic Output Optoisolators Feature Summary

• High-speed signal transmission capability supporting data rates up to 5 MBd
• Push-pull totem pole output configuration for robust digital signaling
• Integrated input protection diode for enhanced circuit reliability
• High common-mode transient immunity (CMTI) for noise-sensitive environments

Logic Output Optoisolators Applications

• Industrial communication bus interfaces
• Isolated digital signal transmission in noisy environments
• Power supply feedback loops requiring high speed
• Microcontroller I/O isolation

Logic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., -300E) against the manufacturer's latest datasheet to confirm packaging type and RoHS compliance status. Ensure the procurement channel provides original component traceability documentation. Cross-reference the part number with official Broadcom catalogs to avoid counterfeit components, as variations exist within the HCPL family regarding pinout and electrical tolerances.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required alongside low propagation delay. The push-pull output eliminates the need for external pull-up resistors, simplifying PCB layout compared to open-collector alternatives. Consider the 3750 Vrms isolation rating for safety compliance in mains-connected applications. Verify that the 5 mA drive current aligns with the source logic levels available in the design.

Logic Output Optoisolators Part Context

This device belongs to the HCPL-2200 series of high-speed optocouplers designed for demanding industrial and commercial applications. The series is characterized by its ability to provide reliable galvanic isolation while maintaining fast signal integrity. The HCPL-2212 variant specifically offers single-channel isolation with a totem pole output, distinguishing it from slower or open-collector variants in the broader Broadcom optocoupler portfolio.
