HCPL-2611-300E

Logic Output Optoisolators Overview

The HCPL-2611-300E is a single-channel high-speed logic gate optocoupler manufactured by Broadcom Limited. It integrates a Gallium Arsenide Phosphide (GaAsP) infrared LED with an integrated high-gain photodetector featuring an open collector Schottky-clamped transistor output. The device supports a data rate of 10 MBd and provides an isolation voltage of 3750 Vrms. Key electrical parameters include a typical forward voltage of 1.5 V, maximum forward current of 10 mA, and output current capability of 50 mA. Propagation delay is typically 24 ns for rise time and 10 ns for fall time. It operates within a temperature range of -40°C to +85°C and is housed in an 8-pin surface-mount DIP package.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix '300E' against the manufacturer's latest datasheet to confirm surface-mount packaging and lead-free compliance. Ensure input current limits do not exceed 10 mA during design validation. Cross-reference isolation ratings with safety standards such as UL 1577 or IEC 60747-5-5 if regulatory certification is required for the final application.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required with a single channel. The open-collector output necessitates an external pull-up resistor for proper logic level generation. Consider the 3750 Vrms isolation barrier for applications requiring moderate galvanic separation between low-voltage logic and higher-voltage power stages.

Logic Output Optoisolators Part Context

This part belongs to the HCPL-2611 series of high-speed optocouplers from Broadcom Limited. The series is designed for applications demanding fast response times and reliable signal transfer across isolated boundaries. The HCPL-2611-300E variant specifically denotes the surface-mount configuration with environmental compliance features.

Logic Output Optoisolators Replacement Considerations

Compatible alternatives may include other single-channel high-speed optocouplers with similar 10 MBd rates and open-collector outputs. Verify pinout compatibility and isolation voltage ratings before substitution. Check for equivalent thermal performance and package dimensions to ensure mechanical fit.
