Product Overview
The LMV393 is a Texas Instruments dual low-voltage comparator in the Signal_Chain category. It provides two comparator channels with open-collector outputs and single-supply operation across the recommended 2.7 to 5.5 V range. Its input common-mode behavior includes ground, with specified common-mode ranges of -0.1 to 2 V at 2.7 V supply and -0.1 to 4.2 V at 5 V supply.
Electrical limits include a 5.5 V absolute maximum supply rating, ±5.5 V differential input voltage absolute maximum, and 0 V to VCC+ absolute maximum input voltage range. The output recommended maximum is VCC+ + 0.3 V. The device is specified for -40 to 125 °C free-air operation, with 150 °C virtual junction and -65 to 150 °C storage limits.
Package data covers LMV393 SOIC (8) at 3.91 mm x 4.90 mm and TSSOP (8) at 3.00 mm x 4.40 mm. Thermal resistance values are specified for D, DDU, DGK, and PW 8-pin packages. The open-collector behavior supports pull-up based output interfacing, where the output sinks current when the negative input is higher than the positive input plus offset.

Procurement Notes
When requesting a quote for LMV393, 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.
