JM38510/10304BPA

Overview

The JM38510/10304BPA is a high-speed differential comparator manufactured by Texas Instruments, belonging to the LM111 series. It features an open-collector and open-emitter output configuration suitable for flexible interfacing. The device operates within a wide supply voltage range of ±15V to 30V and supports a temperature range from -55°C to 125°C. Packaged in an 8-pin ceramic dual in-line package (CDIP), it integrates strobe functionality for precise signal gating. Key electrical characteristics include a low input offset voltage and fast propagation delay, ensuring accurate comparison in demanding environments.

Feature Summary

• Integrates differential comparison with strobe control for precise timing
• Supports open-collector and open-emitter outputs for versatile logic interfacing
• Operates across extended industrial and military temperature ranges
• Utilizes robust ceramic dual in-line packaging for durability

Applications

• High-speed analog-to-digital converter interfaces
• Precision window detector circuits
• Sample-and-hold circuit triggering
• Zero-crossing detection systems

Procurement Notes

Verify the specific suffix 'BPA' corresponds to the required military-grade qualification and ceramic package variant. Confirm that the open-collector/open-emitter output structure aligns with the target system's pull-up requirements. Ensure the operating voltage limits are respected within the specified ±15V to 30V range to maintain performance integrity.

Selection Notes

Select this component when high-speed differential comparison with strobe capability is required in harsh environments. The CDIP package is suitable for applications needing superior thermal stability and mechanical robustness compared to plastic variants. Consider the output configuration needs; if push-pull outputs are preferred, alternative parts in the LM111 family may be more appropriate.

Part Context

This part is a military-grade version of the LM111 comparator, designated under the JM38510 specification. It belongs to the ALS series logic family context but functions as a linear comparator. The device is designed for reliability in aerospace and defense applications where extended temperature operation and radiation hardness are critical factors.

Replacement Considerations

Direct substitutes include other LM111 variants with compatible pinouts and output structures. Verify that any replacement maintains the open-collector/open-emitter output type and the 8-CDIP package form factor. Ensure the substitute meets the same -55°C to 125°C temperature rating.
