HCPL2611SDM

Logic Output Optoisolators Overview

The HCPL2611SDM is a high-speed logic gate optocoupler from onsemi, featuring a single channel with an open collector output. It operates at data rates up to 10 Mbps and provides 5000 Vrms isolation voltage. The device includes an enable input for gating functionality and offers a common mode transient immunity (CMTI) of 10 kV/µs. It functions within a supply voltage range of 4.5V to 5.5V and supports a working temperature range of -40°C to +85°C. Packaged in an 8-SMD surface-mount format, it integrates a GaAsP LED with a high-gain photodetector.

Logic Output Optoisolators Feature Summary

• Integrates an enable input to allow precise signal gating and control of the output state.
• Features internal interference shielding to deliver high common mode transient immunity for noise rejection.
• Utilizes an open collector Schottky-clamped transistor output to facilitate wired-OR configurations.

Logic Output Optoisolators Applications

• High-speed logic interface isolation
• Microprocessor system communication links
• Ground loop elimination in instrumentation

Logic Output Optoisolators Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and insulation ratings. Ensure compatibility with required isolation standards such as UL 1577 or IEC 60747-5-5. Confirm operating temperature ranges match application constraints. Check for RoHS compliance status if environmental regulations apply. Validate pinout alignment for surface-mount integration.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required alongside robust noise immunity. The open collector output allows flexible interfacing with various logic families. Consider the 10 Mbps speed limit for bandwidth requirements. Evaluate the need for the enable pin for power management or signal synchronization. Ensure the 5000 Vrms isolation meets safety clearance distances.

Logic Output Optoisolators Part Context

This part belongs to the HCPL2611 series of high-speed logic gate optocouplers. It shares architectural similarities with other members like HCPL2611VM but differs in packaging. The series is designed for applications demanding fast signal transmission across isolated boundaries while maintaining signal integrity in electrically noisy environments.

Logic Output Optoisolators Replacement Considerations

HCPL2611VM: Different DIP-8 through-hole package; verify mounting compatibility. HCPL2631M: Dual-channel variant; ensure single-channel requirement is met. HCPL2601M: Similar performance but check CMTI specifications carefully.
