HCPL-261N#320

Logic Output Optoisolators Overview

The HCPL-261N#320 is a high-speed optoisolator from Broadcom Limited featuring a single channel with a data rate of 10 MBd. It provides 5000 Vrms isolation voltage and 1 kV/µs common mode transient immunity. The device utilizes an open collector output type with Schottky clamping. Key electrical parameters include a forward current of 10 mA, forward voltage of 1.5 V, reverse voltage of 3 V, and output current of 50 mA. Power dissipation is rated at 60 mW. Transition times are specified as 42 ns rise time and 12 ns fall time.

Logic Output Optoisolators Feature Summary

• High-speed digital signal transmission capability for logic circuits
• Integrated Schottky clamping on the output stage to prevent saturation
• Robust noise immunity against common mode transients

Logic Output Optoisolators Applications

• Digital communication interfaces requiring galvanic isolation
• Microprocessor system isolation
• Signal transmission in noisy industrial environments

Logic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., #320) matches the required package style, as variations exist within the series. Confirm RoHS compliance status if environmental regulations apply to your assembly process. Ensure the supplier provides official datasheets to validate the exact electrical characteristics and pinout configuration before finalizing procurement orders.

Logic Output Optoisolators Selection Notes

Select this component when high-speed data transfer up to 10 MBd is required alongside significant isolation voltage. The open collector output with Schottky clamping makes it suitable for driving logic inputs directly without slow turn-off delays. Consider the through-hole PDIP-8 package constraints during PCB layout design compared to surface mount alternatives available in the same family.

Logic Output Optoisolators Part Context

This part belongs to the HCPL-261N series of high-speed optocouplers manufactured by Broadcom Limited. The series is designed for applications demanding fast switching speeds and reliable signal integrity across isolation barriers. Variants within the series may differ in packaging or specific electrical tolerances while maintaining the core high-speed architecture.

Logic Output Optoisolators Replacement Considerations

Direct substitutes within the HCPL-261N series include HCPL-261N-320E and HCPL-261N-500E. Verify that any replacement maintains the 10 MBd data rate and compatible output configuration. Cross-referencing pinouts and isolation ratings is essential when substituting with components from other manufacturers.
