On the TL331KDBVR comparator, how do the device parameters vary at VCC = 3.3V? All characterization data in the datasheet is at VCC = 5V.

Rustin,
The 3.3V performance is nearly identical to 5V. The upper input common mode range varies with VCC. At 3.3V supply one input must remain within 0V to 1.8V for a valid output.
