HCPL-193K

Logic Output Optoisolators Overview

The HCPL-193K is a dual-channel, hermetically sealed high-speed optocoupler designed for high-reliability applications. It features a 16-pin ceramic DIP package and supports data rates up to 10 MBd with a typical propagation delay of 45 ns. The device provides 1500 VDC isolation voltage and offers common-mode transient immunity of 1000 V/µs. Operating temperatures range from -55°C to +125°C. Each channel integrates a GaAsP LED, input current regulator, and high-gain photodetector with open-collector Schottky-clamped outputs compatible with TTL logic levels.

Logic Output Optoisolators Feature Summary

• Hermetically sealed construction in a 16-pin ceramic DIP package ensures high reliability and environmental stability.
• Integrated input current regulators clamp line voltages and manage LED current to prevent interference from line reflections.
• Internal detector shielding provides guaranteed common-mode transient immunity of 1000 V/µs for noise-resistant signal transmission.
• Open-collector Schottky-clamped transistor outputs are directly compatible with standard TTL logic interfaces.

Logic Output Optoisolators Applications

• Military and aerospace systems requiring MIL-PRF-38534 compliance
• Industrial control systems demanding high isolation and noise immunity
• Digital signal isolation in harsh electromagnetic environments
• Ground loop elimination in sensitive measurement circuits

Logic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., #100, #200) to confirm pin plating and package configuration details. Ensure the procurement source provides documentation confirming MIL-PRF-38534 certification if military-grade reliability is required. Cross-reference the datasheet specifications against your system's voltage and temperature constraints before finalizing orders.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required alongside extreme environmental durability. The integrated current regulators make it suitable for long-line receiver applications where signal integrity is critical. Consider the 16-pin ceramic package size and thermal characteristics for PCB layout compatibility.

Logic Output Optoisolators Part Context

The HCPL-193K belongs to the HCPL-193X series of dual-channel line receiver optocouplers. This family is characterized by hermetic sealing and high common-mode rejection capabilities. It serves as a robust solution for interfacing digital logic across isolated boundaries in demanding operational scenarios.

Logic Output Optoisolators Replacement Considerations

Substitutes must match the 16-pin ceramic DIP form factor and dual-channel architecture. Verify that alternative devices offer comparable 10 MBd speed, 1500 VDC isolation, and -55°C to +125°C operating ranges. Check for equivalent input current regulation and output logic compatibility.
