Overview
The LM139AJ/883 is a quad differential voltage comparator manufactured by Texas Instruments, designed for high-reliability applications. It features four independent comparators within a single package, utilizing a ceramic dual flatpack (CDIP) housing suitable for through-hole mounting. The device operates with an open-collector output configuration and supports a maximum supply voltage of 36V. Key electrical specifications include a typical response time of 1.3 microseconds and a wide operating temperature range extending from -55°C to +125°C.
Feature Summary
- Quad differential voltage comparison capability
- High-reliability military-grade construction
- Wide operating temperature range
Applications
- Military aerospace systems
- Spacecraft instrumentation
- Radiation-hardened electronic circuits
Procurement Notes
Verify the specific suffix /883 indicates compliance with MIL-PRF-38534 or equivalent military standards. Confirm that the ceramic package provides necessary hermetic sealing for the intended environment. Ensure the open-collector outputs match the system logic requirements without additional pull-up components.
Selection Notes
Select this component when radiation hardness and extreme temperature stability are critical. The CDIP package offers mechanical robustness compared to plastic variants. Verify that the 36V maximum supply rating aligns with the power distribution network. Consider the 1.3 microsecond response time for signal processing speed requirements.
Part Context
This part belongs to the LM139 family of analog comparators. The /883 designation typically signifies a batch-controlled version meeting strict military quality and reliability standards. It shares functional similarities with commercial LM139 variants but differs in packaging material and manufacturing controls.
