HCPL2601M

Logic Output Optoisolators Overview

The HCPL2601M is a single-channel high-speed logic gate optocoupler manufactured by onsemi. It integrates an 850 nm AlGaAs LED with a high-speed integrated photo-detector logic gate featuring a strobable output. The device supports data rates up to 10 MBit/s and offers superior common-mode rejection of 10 kV/µs. Key electrical parameters include a maximum propagation delay of 75 ns, a typical forward voltage of 1.4 V, and a maximum DC forward current of 30 mA. It provides a minimum output sink current of 13 mA at a 5 mA input, ensuring a fan-out of 8. The unit operates within a temperature range of -40°C to +85°C and is housed in an 8-pin PDIP package.

Logic Output Optoisolators Procurement Notes

Verify the specific manufacturer source, as this component family has been produced by multiple vendors including Fairchild Semiconductor and Broadcom. Confirm RoHS compliance status and lead time requirements directly with the supplier, as production cycles may vary significantly between original equipment manufacturers and third-party distributors. Ensure the ordering suffix matches the required packaging format.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required with a simple single-channel configuration. The open-collector output allows for easy integration into various logic families without additional buffering. Consider the 10 kV/µs common-mode rejection capability if the application involves rapid voltage transients near the isolation boundary. Verify that the 5 mA input drive capability aligns with the source microcontroller or logic gate output specifications.

Logic Output Optoisolators Part Context

This part belongs to the HCPL2601 series of high-speed logic gate optocouplers. It serves as a direct functional replacement for legacy devices like the 6N137, offering comparable speed and interface characteristics. The series is widely utilized in industrial automation and computing peripherals where reliable galvanic isolation between low-voltage digital circuits and higher-voltage domains is essential.

Logic Output Optoisolators Replacement Considerations

HCPL2601TVM is listed as a parameter-equivalent substitute from onsemi. Cross-reference pinouts and electrical tolerances carefully when substituting parts from different manufacturers such as Fairchild or Broadcom to ensure compatibility with existing PCB footprints and drive circuits.
