Overview
The LM139J/883/MPGD is a quad differential comparator manufactured by Texas Instruments, designed for high-reliability applications. It features four independent comparators in a 14-lead ceramic dual in-line package (CDIP). The device operates with a single power supply ranging from 2V to 36V or dual supplies of ±1V to ±18V. Key electrical specifications include a maximum input offset voltage of 9mV and a typical response time of 1.3μs. It supports an open-collector output configuration and functions within a temperature range of -55°C to +125°C.
Feature Summary
- Contains four independent high-gain differential comparators optimized for wide voltage range operation
- Features open-collector outputs allowing flexible wired-AND logic connections
- Designed for military-grade reliability with ceramic dual in-line packaging
Applications
- Military and aerospace electronic systems requiring high reliability
- Industrial control circuits utilizing wide voltage range comparators
- Precision measurement instrumentation needing low offset voltage performance
Procurement Notes
Verify the specific suffix /883/MPGD against the manufacturer's current datasheet to confirm compliance with MIL-STD-883 standards and hermetic sealing requirements. Ensure the ordering information matches the exact ceramic package variant intended for your design. Cross-reference the revision level to guarantee compatibility with existing system specifications.
Selection Notes
Select this component when military-grade environmental resilience and long-term stability are required. The ceramic package provides superior protection against moisture and mechanical stress compared to plastic variants. Consider the open-collector output structure for interfacing with different logic families without additional level shifting components.
Part Context
This part belongs to the LM139 family of quad differential comparators, originally developed by National Semiconductor and now produced by Texas Instruments. The LM139 series is widely recognized for its low power consumption and ability to operate from single or dual power supplies. The /883/MPGD designation indicates a specific military-grade version with enhanced quality controls.
Replacement Considerations
Direct replacements include other military-grade quad comparators such as the LM139A-MIL or LM139-MIL. Verify pinout compatibility and electrical parameters before substitution. Alternative commercial grade parts like the LM139DR may require package adaptation and do not meet the same environmental standards.
