Last line of section 8.4 of datasheet says to tie all three pins to ground.

Strange. The datasheet I have from TI does not have an 8.4 and does not mention what to do with the pins.
Weird that they have multiple versions.
Yours was updated more recently than mine (far right date). I think mine was for the tin can version of the op amp. The pinout on the example circuit board is round.Mine is SLCS005Y –OCTOBER 1979–REVISED JUNE 2015
Yours SNOSBJ6F–OCTOBER1999–REVISED DECEMBER 2014
Looks like mine might be outdated. Wonder why it is still posted?

The data sheet say they should be tied directly to (-) power rail with no resistors.do not let them float ,pull them to ground with 1-2 k Resistor.
if you let them float,in some area with high frequency generating source ,your circuit might be erratic from noise interference.
Resistors serve no purpose and are not needed.
Output is open collector so it certainly shouldn't hurt that. That was going to be one of my follow ups so thanks everyone.The data sheet say they should be tied directly to (-) power rail with no resistors.
It can be found in section 7.4 or 8.1Strange. The datasheet I have from TI does not have an 8.4 and does not mention what to do with the pins.
Thanks!
