LM760J/883

Overview

The LM760J/883 is a high-speed differential comparator manufactured by National Semiconductor. It features a voltage-feedback architecture and is housed in an 8-pin ceramic dual in-line package (DIP). The device operates with a maximum supply voltage of 36 V and supports a wide common-mode input range from -14 V to +22 V. It delivers a typical slew rate of 15 V/µs and has a propagation delay of 15 ns. The unit functions within a temperature range of -55 °C to 125 °C.

Feature Summary

• High-speed differential comparison capability
• Wide common-mode input voltage range
• Ceramic dual in-line packaging for durability

Applications

• Fast analog-to-digital conversion interfaces
• Threshold detection circuits
• Voltage monitoring systems

Procurement Notes

Verify the specific suffix J/883 indicates compliance with MIL-STD-883 standards. Confirm that the ceramic DIP package matches the required mechanical constraints. Ensure the supplier provides traceability documentation for military-grade components. Check for lot date codes to verify component age and storage history. Validate that the part number corresponds exactly to the National Semiconductor original manufacturing specifications.

Selection Notes

Select this component when high-speed response is critical compared to standard operational amplifiers. Consider the wide common-mode range for applications involving large signal swings. Evaluate the ceramic package requirements against environmental stress conditions. Compare propagation delay specifications against system timing budgets. Assess power supply voltage limits to ensure safe operation within the 36 V maximum rating.

Part Context

This device belongs to the family of high-speed comparators designed for rapid signal processing. It differs from operational amplifiers by lacking internal frequency compensation, allowing for faster switching speeds. The J/883 designation typically denotes a military-grade version with enhanced reliability standards. It serves as a fundamental building block for precision timing and threshold sensing applications.

Replacement Considerations

The UA760 is a documented equivalent from Fairchild Semiconductor. The TL714C offers similar high-speed performance from Texas Instruments. Verify pinout compatibility before substituting these alternatives. Ensure electrical parameters meet or exceed the original design requirements.
