I'm using a TS974 quad op amp wired as a voltage follower to buffer a pot for an ADC. Vcc is connected to 9V and Vdd to 0V. When the voltage at the non-inverting terminal gets to about .7V above Vdd, the output voltage goes to Vcc. I've tested 3 chips in and out of circuit and with dual supplies at ±2.5V and get the same results.
Has anyone seen an op amp behave like this before? Am I damaging the chips some how or am I just missing something?
Here is the datasheet

Thanks for your help.
