Product Overview
The Texas Instruments LMV331 is a single low-voltage comparator in the Signal_Chain category. It integrates one comparator channel and an open-collector output, supporting single-supply operation from 2.7 to 5.5 V. The open-collector output allows external pullup selection while the device performs voltage threshold comparison in low-voltage analog and mixed-signal designs.
Electrical limits include a 5.5 V absolute maximum supply rating, ±5.5 V differential input voltage rating, and an input voltage absolute maximum range from 0 V to VCC+. Recommended operating free-air temperature is -40 to 125 °C, with storage from -65 to 150 °C and a 150 °C operating virtual junction temperature limit.
For compact assembly, LMV331 is listed in SC-70 (5) 1.25 mm x 2.00 mm and SOT-23 (5) 1.60 mm x 2.90 mm package cases. Thermal resistance junction-to-ambient is 224 °C/W for the DBV 5-pin package and 238 °C/W for the DCK 5-pin package. Applications include threshold detection, level comparison, low-voltage monitoring, and open-collector logic interface circuits.

Procurement Notes
When requesting a quote for LMV331, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
FAQ
What type of device is the LMV331?
The LMV331 is a Texas Instruments single low-voltage comparator in the Signal_Chain category. The extracted facts specify one comparator channel and an open-collector output, with recommended single-supply operation from 2.7 to 5.5 V.
