HCPL-2601#320

Logic Output Optoisolators Overview

The HCPL-2601#320 is a single-channel high-speed optocoupler from the Broadcom HCPL series, designed for digital isolation applications. It integrates an AlGaAs infrared LED with a high-gain photodetector and CMOS logic output circuitry. Key electrical parameters include a data rate of 10 MBd, an isolation voltage of 5000 Vrms, and a common mode transient immunity of 10 kV/µs. The device features an open collector output capable of sourcing up to 50 mA, with a typical rise time of 24 ns and fall time of 10 ns. Operating temperature ranges from -40°C to +85°C.

Logic Output Optoisolators Feature Summary

• Integrates an AlGaAs infrared LED with a high-gain photodetector and CMOS logic output for fast signal transmission.
• Features an open collector output structure with Schottky clamping to support wired-OR connections and robust noise immunity.
• Provides high common mode transient immunity to maintain signal integrity in electrically noisy industrial environments.

Logic Output Optoisolators Applications

• Microprocessor system isolation
• Industrial communication bus isolation protection
• Ground loop elimination in sensor interfaces

Logic Output Optoisolators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to widespread counterfeiting risks in legacy semiconductor markets. Confirm RoHS compliance status and specific suffix variations (e.g., E for lead-free) against current datasheets. Check production lifecycle status as this model may be classified as obsolete or not for new designs by some manufacturers. Ensure storage conditions adhere to moisture sensitivity levels if applicable.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation exceeding 10 MBd is required alongside strong noise rejection capabilities. The open collector output necessitates external pull-up resistors, which must be sized according to the target logic family voltage levels. Consider thermal dissipation limits within the PDIP-8 package for continuous operation near maximum junction temperatures.

Logic Output Optoisolators Part Context
