Product details

Dual comparator with low-voltage operation and 600 ns response

The Texas Instruments LMV393MMX is a dual-channel general-purpose comparator. Each comparator can sink up to 84 mA at 5 V. The 600 ns maximum propagation delay suits moderate-speed threshold detection. Output options include CMOS, open-collector, and TTL. Packaged in an 8-VSSOP footprint.

The 600 ns propagation delay is the dynamic limit. The 300 µA quiescent current per channel keeps the total under 600 µA. Input offset voltage is 7 mV max at 5 V.

Package and mounting: 8-VSSOP (MSOP-8)

The LMV393MMX comes in an 8-VSSOP package (3.00 mm body width, 0.118" pitch). Surface-mount only. The 8-VSSOP footprint is shared with many other dual comparators and op-amps. Soldering profile follows standard MSOP reflow guidelines.

This covers most factory-floor automation, outdoor telecom cabinets, and HVAC controllers. Not qualified to AEC-Q100, so not recommended for automotive under-hood or passenger-cabin applications without independent qualification.

Frequently asked questions

What is the difference between LMV393MMX and LMV393MM?

The LMV393MMX and LMV393MM share the same dual comparator core and electrical specifications. The suffix difference typically indicates packaging or reel configuration — confirm the exact package marking and tape/reel quantity before ordering to ensure BOM fit.

Can the LMV393MMX replace a standard LM393?

The LMV393MMX is a low-voltage derivative of the classic LM393. It operates down to 2.7 V (vs the LM393's minimum of 2 V or 3 V depending on variant) and has a lower quiescent current of 300 µA. Pin-compatible in the same 8-pin MSOP footprint, but check the supply range and output drive requirements against your existing LM393 circuit.

What is the exact pinout of LMV393MMX?

The LMV393MMX uses the standard dual comparator pinout for 8-VSSOP: pin 1 = OUT A, pin 2 = IN- A, pin 3 = IN+ A, pin 4 = GND, pin 5 = IN+ B, pin 6 = IN- B, pin 7 = OUT B, pin 8 = V+. This matches the industry-standard LM393/MSOP-8 layout.
