M38510/11202BPA

Overview

The M38510/11202BPA is a dual differential comparator manufactured by Texas Instruments under the LM193-MIL series. It operates from single or dual supplies with a voltage range of 2 V to 36 V. The device features low supply current drain, low input bias and offset currents, and an open-drain output compatible with TTL, MOS, and CMOS logic. It is characterized for operation across a temperature range of -55°C to +125°C.

Feature Summary

• Dual independent voltage comparators designed for wide single-supply or dual supply operation
• Open-drain outputs allow wired-AND functionality and flexible logic level interfacing
• Input common-mode voltage range includes ground potential
• Differential input voltage range matches maximum-rated supply voltage

Applications

• Chemical or gas sensor signal conditioning
• Desktop PC system monitoring
• AC induction motor control circuits
• Precision weigh scale interfaces

Procurement Notes

Verify that the component meets MIL-PRF-38535 specifications if military-grade compliance is required. Confirm package type availability as options include CDIP and LCCC. Ensure design accounts for the specified operating temperature range and absolute maximum ratings to maintain reliability in harsh environments.

Selection Notes

Select this component when high voltage tolerance up to 36 V is necessary alongside low power consumption. The open-drain architecture suits applications requiring multiple comparators to share a common bus line. Consider the specific package constraints, such as ceramic dual in-line or leadless ceramic chip carrier, based on thermal and mechanical requirements.

Part Context

This part belongs to the LM193-MIL family, which provides dual differential comparators optimized for rugged environments. It shares functional similarities with commercial variants like the LM293 but offers extended temperature ranges and stricter parameter testing suitable for aerospace and defense applications.

Replacement Considerations

JM38510/11202BGA is a confirmed substitute within the same family offering similar dual comparator functionality.
