Does TS880has "No phase reversal" function?

When the comparator input pins exceed V+ or GND, will the output of the comparator has phase-inversion?

Thanks!

Hello,

There isn't "no phase reversal function" on TS880. For example, there is phase reversal on the picture below with In- at GND, and VIn+ from 0.2V to -2V. Output return on High state when Vin+ is lower than 1V.
Limit the current or add a Schottky diode on the inputs could avoid the phase reversal of the product.
