HCPL-5430#300

Logic Output Optoisolators Overview

The HCPL-5430#300 is a commercial-grade, two-channel high-speed optocoupler housed in an 8-pin hermetically sealed ceramic DIP package. It features push-pull totem pole outputs with a data rate of 40 Mbps and isolation voltage of 1500 VDC. Key electrical parameters include a forward current of 10 mA, forward voltage of 1.35 V, output current of 25 mA, and power dissipation of 200 mW. Propagation delays are typically 60 ns for both low-to-high and high-to-low transitions. The device operates within a temperature range of -55°C to +125°C.

Logic Output Optoisolators Feature Summary

• Hermetically sealed construction using ceramic packaging for enhanced reliability
• High-speed digital signal transmission capability at 40 Mbps
• Push-pull totem pole output configuration for robust logic interfacing

Logic Output Optoisolators Applications

• Industrial communication systems requiring galvanic isolation
• Data acquisition systems with high noise immunity needs
• Medical equipment requiring strict safety isolation standards

Logic Output Optoisolators Procurement Notes

Verify the specific suffix #300 indicates the lead finish type, as this affects solderability and handling requirements. Confirm that the hermetic seal integrity meets your environmental specifications. Ensure compatibility with standard DIP-8 footprints during PCB layout. Check for RoHS compliance status if required by your manufacturing regulations. Validate supplier authenticity due to the specialized nature of hermetic components.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is critical alongside long-term reliability in harsh environments. The ceramic package offers superior thermal stability compared to plastic alternatives. Consider the 40 Mbps speed limit against your system's maximum data throughput requirements. Evaluate the 1500 VDC isolation rating against your circuit's voltage stress levels. Ensure the push-pull output drive strength matches your load requirements.

Logic Output Optoisolators Part Context

This part belongs to Broadcom's HCPL-543K series of high-speed optocouplers. The series is designed for applications demanding fast response times and reliable signal transmission across isolated boundaries. The hermetic sealing distinguishes it from non-sealed variants, targeting aerospace, military, or industrial sectors where moisture ingress must be prevented.

Logic Output Optoisolators Replacement Considerations

Direct replacements may include other hermetically sealed dual-channel optocouplers from the same family, such as HCPL-5430 without specific suffix variations if lead finishes match. Verify pinout compatibility and electrical parameter equivalence before substitution.
