HCPL-5300

Logic Output Optoisolators Overview

The HCPL-5300 is a hermetically sealed, logic output optocoupler from Broadcom Limited. It features an open collector output with Schottky clamping for high-speed performance. The device operates over the full military temperature range of -55°C to 125°C. Key electrical parameters include a current transfer ratio (CTR) of 90%, a propagation delay of 450ns, and a typical common-mode transient immunity (CMTI) of 10kV/µs. It supports a maximum continuous output current of 15mA and has a power dissipation rating of 145mW.

Logic Output Optoisolators Feature Summary

• Hermetically sealed construction in an 8-pin ceramic DIP package suitable for harsh environments
• Schottky-clamped open collector output design ensures fast switching speeds and reduced storage time
• High common-mode transient immunity capability for reliable noise rejection in digital systems

Logic Output Optoisolators Applications

• Military and aerospace digital isolation circuits
• High-speed data transmission interfaces requiring hermetic sealing
• Industrial control systems operating under extreme temperature conditions

Logic Output Optoisolators Procurement Notes

Verify the specific ordering suffix to confirm lead configuration options such as gold-plated or solder-dipped leads. Ensure the procurement specification explicitly requires hermetic sealing and military-grade temperature range compliance. Confirm that the open collector output type matches the system interface requirements before finalizing the order.

Logic Output Optoisolators Selection Notes

Select this component when hermetic sealing and wide temperature operation are mandatory. The Schottky clamp provides superior speed compared to standard logic outputs. Verify that the 15mA output current capacity meets the load requirements. Consider the 8-CDIP package dimensions for PCB layout compatibility in constrained military or industrial enclosures.

Logic Output Optoisolators Part Context

This part belongs to the HCPL-5301 series of logic output optocouplers. It shares functional similarities with the HCPL-5301 but differs in packaging and sealing specifications. The series is designed for applications requiring robust signal isolation between low-voltage logic circuits and higher voltage domains.

Logic Output Optoisolators Replacement Considerations

The HCPL-5301 is a related commercial grade variant within the same series. Direct substitution requires verifying if hermetic sealing is strictly necessary for the application environment.
