3PEAK LMV393 Fake/Out of spec part?

[ACharnley]

Just checking if I'm missed something regarding this part which looks like it's out of spec or not working at all.

LMV393TP-SR 3PEAK $0.1343 - SOIC-8 Comparators ROHS datasheet, price, inventory C97672

The relevant bits, the datasheet says it has a 3.5mV input offset (max) and a -0.2 to +0.2v common input range.

With a 5v vdd, 140mV reference and a low frequency signal which clearly rises and falls below this always receive a pull down at the output.

Do you have a pull-up resistor at the output?

Apologies I thought I edited it to include that, there's a 10k pull-up. I double checked it was ok when I last swapped out one of the LMV's.
