HCPL-5230

Logic Output Optoisolators Overview

The HCPL-5230 is a dual-channel, hermetically sealed high-speed optocoupler manufactured by Broadcom Limited. It features an 8-pin ceramic DIP package with gold-plated or solder-dipped leads, complying with MIL-PRF-38534 standards. The device supports a data rate of 5 Mb/s and offers a common-mode transient immunity of 1000 V/µs. Key electrical parameters include a maximum propagation delay of 350 ns, a forward current of 8 mA, and a continuous output current of 15 mA. It operates within a temperature range of -55°C to +125°C and provides an isolation voltage of 1500 VDC.

Logic Output Optoisolators Feature Summary

• Hermetically sealed construction in a ceramic DIP package for high reliability in harsh environments
• Push-pull totem pole output structure supporting three-state operation and direct bus driving
• High common-mode transient immunity with internal shielding to eliminate signal jitter
• Compatible with LSTTL, TTL, and CMOS logic interfaces across a wide supply voltage range

Logic Output Optoisolators Applications

• High-speed line receivers in industrial systems
• Isolated bus drivers for computer peripherals
• Replacement for pulse transformers in signal isolation
• Elimination of ground loops in sensitive electronic circuits

Logic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., #300) against the required lead finish, as options include gold-plated or solder-dipped variants. Confirm RoHS compliance status, as some military-grade versions may not meet standard environmental directives. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability for MIL-PRF-38534 certified components.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required alongside strict environmental durability. The push-pull output architecture is suitable for driving low-impedance loads directly. Consider the wide operating temperature range for aerospace or defense applications. Verify that the 5 Mb/s data rate meets system timing requirements before choosing over slower or faster alternatives.

Logic Output Optoisolators Part Context

This part belongs to the HCPL series of high-speed optocouplers designed for commercial and military use. It represents a legacy product line originally developed by Avago Technologies and Hewlett-Packard, now maintained by Broadcom. The series is characterized by its robust hermetic sealing and compatibility with standard logic families, serving as a bridge between isolated digital domains.

Logic Output Optoisolators Replacement Considerations

Direct substitutes must match the 8-pin CDIP package and MIL-PRF-38534 qualification. Check equivalent parts from other manufacturers offering hermetically sealed dual-channel optocouplers with similar 5 Mb/s speeds and 1500 VDC isolation. Ensure pinout compatibility and identical output drive capabilities to maintain circuit integrity without redesign.
