Overview
The LM139 MD8 is a voltage comparator die from Texas Instruments. It features a single channel with open collector and open drain outputs. The device operates within a supply voltage range of 2V to 36V. It supports a common-mode input voltage range extending down to 0.5V. The unit has a maximum propagation delay of 0.2 microseconds. Input offset voltage is limited to 3mV at 25°C. The component functions across an operating temperature range of -55°C to +125°C.
Feature Summary
- Single-channel differential voltage comparison capability
- Open collector and open drain output configuration for flexible interfacing
- Wide common-mode input voltage range including ground reference
Applications
- Military aerospace electronics requiring radiation hardening
- Heavy ion single event transient testing environments
- Proton irradiation susceptibility analysis for space systems
Procurement Notes
Verify the specific revision code associated with the MD8 designation against official Texas Instruments documentation. Confirm that the die form factor meets your packaging requirements, as this is not a standard packaged IC. Ensure compatibility with your wire bonding or flip-chip assembly processes before procurement.
Selection Notes
Select this component when a single-channel comparator is required for high-reliability applications. The wide operating temperature range suits extreme environments. Verify that the open-drain output structure aligns with your logic interface needs. Consider the die format implications for your manufacturing line compared to packaged alternatives.
Part Context
This part belongs to the LM139 family of quad differential comparators manufactured by Texas Instruments. While the standard LM139 contains four channels in a package, the LM139 MD8 represents the bare die variant. This form factor is typically utilized in hybrid microcircuits or custom packaging solutions for specialized industrial or military applications.
Replacement Considerations
