HCPL2601

Logic Output Optoisolators Overview

The HCPL2601 is a single-channel high-speed logic gate optocoupler manufactured by onsemi. It consists of an 850nm AlGaAS LED optically coupled to a high-speed photodetector with an open collector output stage. This configuration permits wired OR outputs and ensures TTL compatibility. The device provides superior common mode rejection, typically 10kV/µs, due to an internal noise shield. Coupled parameters are guaranteed over the temperature range of -40°C to +85°C.

Logic Output Optoisolators Procurement Notes

Verify the specific ordering suffix against official onsemi documentation to confirm package type and tape/reel specifications. Ensure the component meets the required temperature grade for your application environment. Cross-reference part numbers carefully as legacy Fairchild branding may appear in older records. Confirm availability status directly with authorized distributors or the manufacturer website.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation with TTL compatibility is required. The open collector output necessitates an external pull-up resistor for proper logic level generation. Consider the common mode rejection requirements of your system to ensure adequate noise immunity. Verify that the input current requirements align with your driving circuit capabilities before implementation.

Logic Output Optoisolators Part Context

This device belongs to the family of high-speed logic gate optocouplers alongside models like the 6N137 and HCPL2611. While sharing similar architectural principles, specific electrical characteristics such as propagation delay and common mode rejection vary between variants. The HCPL2601 specifically targets applications requiring robust isolation with simple logic interface capabilities.

Logic Output Optoisolators Replacement Considerations

The 6N137 and HCPL2611 are documented related single-channel variants within the same product family. Verify pinout compatibility and specific electrical parameter differences before substitution. Check official datasheets for any functional distinctions regarding output drive strength or switching speed.
