AD977 TAG Pin

Question

I am testing an AD977 for use in a DAQ system. Having read the documentation, I can not determine what to do with the TAG signal, if I am not daisy chaining multiple ADCs on the same Data Channel. 
 SHould it be tied high, low, or left floating?

Apologies for missing this query. The TAG input, when unused, should always be tied either high or low and not be allowed to float. 
 However, this product is no longer recommended for new design. Please see https://www.analog.com/en/products/ad7663.html as an alternative. 
 Thanks.
