VO4661

Logic Output Optoisolators Overview

The VO4661 is a dual-channel high-speed logic output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an open-drain output configuration with a maximum data rate of 10MBd and a propagation delay of 75ns. The device provides 5300Vrms isolation voltage and a common-mode transient immunity of 15kV/µs. It operates within a supply voltage range of 4.5V to 5.5V and supports a continuous output current of 50mA per channel. The component is housed in an 8-DIP package and functions reliably across a temperature range of -40°C to 100°C.

Logic Output Optoisolators Feature Summary

• Dual-channel architecture providing independent signal isolation paths
• High common-mode transient immunity for noise-resistant operation
• Open-drain output stage compatible with standard logic interfaces
• Fast switching performance suitable for high-speed digital communication

Logic Output Optoisolators Applications

• Industrial control networks with significant ground potential differences
• Microprocessor interface circuits demanding fast signal response
• Power electronics gate drive isolation for noisy environments

Logic Output Optoisolators Procurement Notes

Verify the specific ordering suffix to confirm packaging type, as standard units may differ from tape-and-reel variants. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications. Ensure the 8-DIP through-hole package aligns with PCB footprint constraints. Cross-reference datasheet revisions to validate electrical parameters before finalizing procurement orders.

Logic Output Optoisolators Selection Notes

Select this component when dual-channel isolation with high speed is required. The open-drain output necessitates external pull-up resistors for proper logic level generation. Verify that the 5300Vrms isolation rating meets safety standards for the application voltage. Consider the 75ns propagation delay for timing-critical designs compared to slower alternatives.

Logic Output Optoisolators Part Context

The VO4661 belongs to Vishay's family of high-speed optocouplers designed for robust digital isolation. It shares architectural similarities with single-channel counterparts but integrates two isolated channels in one package. This integration reduces board space while maintaining high isolation performance. The device complements other series components offering similar speed and isolation characteristics.

Logic Output Optoisolators Replacement Considerations

The VO2631 serves as a surface-mount equivalent with identical electrical characteristics but utilizes an 8-SMD package. Verify pin compatibility and thermal management requirements when substituting between DIP and SMD formats. Ensure the replacement maintains the required 15kV/µs CMTI specification for the specific application environment.
