Manufacturing of that part appears to have ceased ca. 1998. Depending on your speed requirements, consider emulating it with a couple of old LM339's and 74HC374.

Hi mneary,
Thanks for your help but the main issue with this solution is, that it will increase the number of ICs in the circuit which I don't want, but to keep this all in single IC. I have to use this IC for sensing Moisture and there are sixteen sensing areas so i have to feed the outputs of all the comparators to MCU port is being used for input as well as output in multiplexing manner that is why tri-state output is required.
