74OL6011

Overview

The onsemi 74OL6011 is a logic output optoisolator from the OPTOLOGIC series, housed in a 6-DIP package. It features one channel with a high data rate of 15MBd and a maximum propagation delay of 180ns (tpLH) and 120ns (tpHL). The device provides 5300Vrms isolation voltage and a minimum common-mode transient immunity of 5kV/µs. It operates within a supply voltage range of 4.5V to 15V and supports an operating temperature range of 0°C to 70°C. The output is open-collector with Schottky clamping, capable of sourcing 40mA per channel.

Feature Summary

• High-speed logic output capability with 15MBd data rate
• Robust electrical isolation with 5300Vrms rating
• Open-collector output structure with integrated Schottky clamping for fast switching
• High common-mode transient immunity of 5kV/µs

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops
• Signal transmission across isolated ground planes
• Microcontroller interface circuits

Procurement Notes

This component is officially marked as obsolete and no longer manufactured by onsemi. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm the specific revision and packaging condition, as availability is limited. Replacement planning is strongly recommended due to the discontinuation status.

Selection Notes

Designers should evaluate the 15MBd data rate and 5300Vrms isolation requirements against current project needs. The open-collector output necessitates external pull-up resistors, which impact speed and power consumption. Consider the 4.5V to 15V supply range compatibility with existing logic levels. Given the obsolete status, alternative components with similar pinouts and electrical characteristics should be identified for new designs.

Part Context

The 74OL6011 belongs to onsemi's OPTOLOGIC family, designed for high-speed digital isolation applications. It complements other devices like the 74OL6000, 74OL6010, and 74OL6011 variants within the same series. These components are engineered to provide reliable signal transfer between isolated circuits while maintaining high noise immunity and fast response times in demanding electronic environments.

Replacement Considerations

The HCPL-2200 from Broadcom Limited is documented as a similar available substitute. Designers should verify pinout compatibility and electrical parameter alignment before substitution.
