5962R9452602VGA

Overview

The 5962R9452602VGA is a general-purpose comparator manufactured by National Semiconductor, now part of Microchip Technology. This component features two independent comparison elements housed in a TO-99-8 metal can package. It supports versatile logic compatibility, including CMOS, DTL, ECL, MOS, and TTL output types. The device operates with a single or dual power supply ranging from 2V to 36V, or ±1V to ±18V. Designed for robust performance, it functions within an operating temperature range of -55°C to 125°C. The output configuration is open-collector, facilitating flexible interfacing with various digital systems.

Feature Summary

• Dual-element architecture providing two independent comparators in a single package
• Wide supply voltage capability supporting both single and dual rail configurations
• Broad logic family compatibility ensuring interoperability with CMOS, DTL, ECL, MOS, and TTL standards
• Industrial-grade thermal stability suitable for extreme environmental conditions

Applications

• High-speed signal processing circuits requiring precise voltage threshold detection
• Interface adapters between different logic families such as TTL and CMOS
• Over-voltage and under-voltage protection monitoring systems
• Waveform generation and pulse width modulation control loops

Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor assets were acquired by Microchip Technology. Confirm the specific suffix 'VGA' corresponds to the required military or extended temperature grade specifications. Ensure the TO-99-8 metal can package matches your board layout constraints. Check for RoHS compliance status if required by your manufacturing standards, as legacy parts may have different regulatory classifications. Validate the open-collector output requirements against your downstream circuit design.

Selection Notes

Select this component when dual comparators are needed in a radiation-hardened or high-reliability environment. The TO-99-8 package offers superior thermal dissipation and hermetic sealing compared to plastic alternatives. Consider the wide supply voltage range if your system experiences significant rail fluctuations. The multi-logic compatibility reduces the need for level-shifting components. Evaluate the open-collector output against your pull-up resistor requirements and switching speed needs.

Part Context

This part belongs to the broader category of linear comparators produced by National Semiconductor. The 5962 prefix indicates a military-grade or high-reliability variant often subject to strict quality control standards. As a legacy product, it represents established analog design principles before the widespread adoption of modern low-power CMOS comparators. Its continued availability supports maintenance of critical infrastructure and defense systems where component obsolescence must be managed carefully.

Replacement Considerations

Direct pin-compatible replacements may include other dual comparators in TO-99 packages from manufacturers like Analog Devices or Texas Instruments. Verify that any substitute maintains the same supply voltage range and logic compatibility. Ensure the replacement meets the same temperature and reliability standards.
