74OL6000

Overview

The onsemi 74OL6000 is a high-speed logic output optoisolator featuring an octal D-type flip-flop configuration. It provides electrical isolation with a maximum rating of 5300Vrms and supports data rates up to 15MBd. The device operates within a supply voltage range of 4.5V to 15V and includes Schottky clamping for enhanced noise immunity. Key timing parameters include a maximum propagation delay of 180ns for low-to-high transitions and 120ns for high-to-low transitions, with typical rise and fall times of 50ns and 5ns respectively. It offers a minimum common-mode transient immunity of 5kV/µs and functions reliably across an operating temperature range of -40°C to 70°C.

Feature Summary

• Octal D-type flip-flop architecture for multi-channel digital signal processing
• High-speed data transmission capability supporting 15MBd rates
• Integrated Schottky clamping to improve noise immunity and switching performance

Applications

• Industrial control systems requiring isolated digital interfaces
• Data communication equipment needing high-speed signal isolation
• Logic gate applications demanding electrical separation between circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolete status. Confirm package integrity and pin alignment against the 6-DIP specification. Request batch-specific test reports to ensure compliance with historical manufacturing standards. Validate that the unit matches the original 74OL6000 designation rather than updated variants. Check for any specific handling requirements related to electrostatic discharge protection during storage and installation.

Selection Notes

Choose this component when designing systems that require isolated octal D-type flip-flops with high-speed logic output capabilities. Ensure the application environment stays within the specified -40°C to 70°C operating temperature range. Verify that the required isolation voltage does not exceed 5300Vrms. Consider the 15MBd data rate limit for signal integrity. Confirm compatibility with the 4.5V to 15V supply voltage range. Evaluate the need for Schottky clamping features for noise-sensitive environments.

Part Context

The 74OL6000 belongs to the OPTOLOGIC™ series from onsemi, designed for robust industrial and commercial applications. It represents a legacy solution in the company's standard product lineup, offering reliable performance for established designs. As part of the broader family of logic output optoisolators, it shares architectural similarities with other models like the 74OL6010 but differs in channel configuration. This component was engineered to meet rigorous hardware requirements for high-speed digital isolation.

Replacement Considerations

The 74OL6000 is officially listed as obsolete. Potential substitutes include similar devices such as the HCPL-2200 from Broadcom Limited. Verify functional equivalence regarding pinout, isolation ratings, and timing characteristics before integration.
