HCPL-5430

Logic Output Optoisolators Overview

The HCPL-5430 is a commercial grade, two-channel hermetically sealed optocoupler housed in an 8-pin ceramic DIP package. It features gold-plated and solder-dipped leads for robust connectivity. The device supports a data rate of 40 Mb/s with a propagation delay of 60 ns maximum. Electrical characteristics include a forward current of 10 mA, forward voltage of 1.35 V, and output current capability of 25 mA per channel. It provides 1500 VDC isolation and operates within a temperature range of -55°C to +125°C.

Logic Output Optoisolators Procurement Notes

Verify the specific ordering suffix to confirm lead type availability, as options include gold-plated or solder-dipped variants. Ensure compliance with RoHS directives if required by the target application. Confirm that the ceramic package and hermetic seal meet the environmental specifications for the intended deployment environment before finalizing procurement.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required alongside strict environmental sealing. The dual-channel architecture allows for efficient space utilization in compact designs. Consider the 1500 VDC isolation rating for safety-critical applications. Verify that the 25 mA output current meets the load requirements of the receiving circuitry without additional buffering.

Logic Output Optoisolators Part Context

This part belongs to the HCPL-543K series of high-speed optocouplers manufactured by Broadcom Limited. It represents a legacy product line originally developed by Agilent Technologies, now maintained under Broadcom's portfolio. The series is characterized by its use of gallium arsenide LEDs and silicon phototransistors integrated into a single hermetic package for reliable long-term operation.
