HCPL2601SM

Logic Output Optoisolators Overview

The HCPL2601SM is a single-channel logic output optocoupler manufactured by onsemi. It features an open-collector phototransistor output and supports data rates up to 10 Mbps. The device utilizes surface-mount technology in an 8-pin SOIC package. Key electrical parameters include a maximum propagation delay of 100 ns, a typical rise time of 50 ns, and a typical fall time of 12 ns. It offers a minimum common-mode rejection of 5 kV/µs at VCM = 50 V. The component operates within a temperature range of -40°C to +85°C and provides 2500 Vrms isolation voltage.

Logic Output Optoisolators Feature Summary

• TTL-compatible logic gate output configuration
• Robust noise immunity with high common-mode rejection ratio
• Surface-mount packaging for automated assembly

Logic Output Optoisolators Applications

• Isolated line receiver circuits
• Microprocessor system interfaces
• Computer peripheral interfaces
• Digital isolation for A/D and D/A conversion systems

Logic Output Optoisolators Procurement Notes

Verify the specific suffix 'SM' confirms the surface-mount SOIC-8 package variant rather than through-hole DIP versions. Confirm RoHS compliance status as manufacturing sources may vary. Ensure the supplier provides official datasheets matching the onsemi specification sheet for accurate timing and isolation parameters before finalizing procurement orders.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required between TTL-compatible logic levels. The open-collector output necessitates an external pull-up resistor for proper logic high state generation. Consider the 2500 Vrms isolation rating for safety requirements and verify that the 10 Mbps speed meets the signal bandwidth needs of the application circuit design.

Logic Output Optoisolators Part Context

This part belongs to the HCPL2601 family of high-speed optocouplers designed for robust digital signal transmission across isolated boundaries. It serves as a direct replacement for legacy components like the 6N137 in many applications, offering improved speed and reliability. The series is widely used in industrial and computing environments requiring reliable galvanic isolation.

Logic Output Optoisolators Replacement Considerations

HCPL-2601#300 (Broadcom) is a pin-compatible alternative but typically uses a DIP package; verify package compatibility. HCNW2601 is another compatible option from Broadcom. Ensure substitute parts match the 10 Mbps speed and 2500 Vrms isolation ratings.
