Overview
The LMV331IDCKTE4 is a single-channel general-purpose analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and features an open-drain output capable of sinking up to 10 mA. The device exhibits a propagation delay of 200 ns, a maximum input offset voltage of 7 mV, and a typical quiescent current of 100 µA. It is housed in a compact SC-70-5 surface-mount package and supports an extended operating temperature range from -40°C to +125°C.
Feature Summary
- Low-voltage operation compatible with 2.7 V to 5.5 V power supplies
- Open-drain output configuration for flexible interfacing
- Compact SC-70-5 package design for space-constrained applications
Applications
- Battery-powered systems requiring low current consumption
- Threshold detection circuits
- Signal conditioning for microcontrollers
Procurement Notes
Verify the specific suffix E4 indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm the SC-70-5 package dimensions against PCB footprint requirements. Ensure the open-drain output configuration aligns with the pull-up resistor requirements of the target circuit interface. Check for any recent product change notices regarding marking or packaging updates.
Selection Notes
Select this component when a single comparator with low quiescent current is required in a minimal footprint. The open-drain output allows for level shifting between different voltage domains. Consider the 200 ns propagation delay for timing-sensitive applications. Verify that the 10 mA sink capability meets the load requirements of the connected logic or indicator components.
Part Context
This part belongs to the LMV331 family of low-voltage comparators, which are designed as successors to industry-standard devices like the LM339. The family offers reduced current consumption and smaller package options compared to older generations. The IDCKRE4 variant specifically denotes the tape-and-reel packaging format suitable for automated assembly processes.
Replacement Considerations
LMV331IDCKT is a direct functional equivalent within the same series.
