Overview
The Texas Instruments 5962R0052402VGA is a radiation-hardness-assured (RHA) voltage comparator designed for high-reliability applications. It operates within a supply voltage range of 5V to 30V, with a minimum dual supply voltage of 2.5V. The device features an open-collector output type and provides one channel of comparison. It is housed in an 8-TO-99 package and supports through-hole mounting. The component functions reliably across an operating temperature range of -55°C to +125°C.
Feature Summary
- Radiation-hardness-assured construction for space and defense environments
- Wide single or dual supply voltage operation capability
- Open-collector output configuration for flexible interfacing
- Military-grade temperature range stability
Applications
- Satellite communication systems
- Spacecraft telemetry and control units
- High-altitude unmanned aerial vehicles
- Nuclear instrumentation systems
Procurement Notes
Verify the specific suffix VGA against official Texas Instruments documentation to confirm pinout and electrical characteristics match your design requirements. Ensure that the radiation hardness assurance certification meets the total ionizing dose and single-event upset thresholds required by your mission profile before finalizing procurement.
Selection Notes
Select this component when radiation tolerance is critical and standard commercial comparators are insufficient. The TO-99 package offers robust mechanical integrity for harsh environments. Consider the open-collector output limitations regarding pull-up resistor requirements and switching speed constraints compared to push-pull alternatives.
Part Context
This part belongs to Texas Instruments' military-grade linear IC portfolio, specifically under the LM111QML family. These components are manufactured under strict quality control standards to ensure consistency and reliability in aerospace and defense applications where failure is not an option.
Replacement Considerations
Check for direct equivalents such as the 5962R0052402VZA if package or minor parameter variations are acceptable. Verify compatibility with existing board layouts due to potential differences in lead frame dimensions or thermal characteristics between variants.
