HCPL-261N-020E

Logic Output Optoisolators Overview

The HCPL-261N-020E is a high-speed optocoupler featuring one channel with an open collector output. It supports data rates up to 10 MBd and provides 5000 Vrms isolation voltage. The device operates with a forward current of 10 mA and a forward voltage of 1.5 V. Key timing parameters include a rise time of 42 ns, fall time of 12 ns, and maximum propagation delay of 100 ns. It handles a reverse voltage of 3 V and delivers an output current of 50 mA. The component is housed in an 8-pin PDIP package.

Logic Output Optoisolators Feature Summary

• Provides high-speed signal transmission with a data rate of 10 MBd for efficient digital communication.
• Features Schottky clamped open collector outputs to enhance switching speed and reduce storage time.
• Offers robust electrical isolation with a 5000 Vrms rating to protect low-voltage circuits from high-voltage noise.

Logic Output Optoisolators Applications

• Industrial networking systems requiring galvanic isolation between diverse voltage levels
• General-purpose logic interface applications connecting microcontrollers to power stages
• Signal transmission in environments with high common-mode transient immunity requirements

Logic Output Optoisolators Procurement Notes

Verify the specific suffix (020E) to confirm the tube packaging format and RoHS compliance status. Ensure the procurement source is an authorized distributor to guarantee authenticity. Cross-reference the datasheet revision date against your design requirements. Confirm that the 8-DIP through-hole package aligns with your PCB footprint specifications before finalizing orders.

Logic Output Optoisolators Selection Notes

Select this component when a single-channel high-speed interface is required with significant isolation voltage. It is suitable for designs needing Schottky-clamped outputs to minimize propagation delay variations. Compare its 5000 Vrms rating against lower-rated alternatives if higher insulation is necessary. Consider the 10 MBd limit when evaluating system bandwidth constraints relative to other members of the HCPL-26xx family.

Logic Output Optoisolators Part Context

This part belongs to the Broadcom HCPL-26xx series of high-speed optocouplers. The series is characterized by fast switching speeds and integrated Schottky clamping on the phototransistor outputs. These devices are designed to replace slower optocouplers in modern digital interfaces where signal integrity and speed are critical.

Logic Output Optoisolators Replacement Considerations

The HCPL-2611-020E is a verified substitute within the same series, offering similar 10 MBd performance but with a 3750 Vrms isolation rating instead of 5000 Vrms. Verify that the reduced isolation voltage meets the safety requirements of the target application before substitution.
