Acrobat does not provide any native capability of conversion of PDF files to multiple page TIFF files. The reason for this is quite simple. Multiple page TIFF files are not supported by the majority of applications that produce and/or consume TIFF files. Most multiple page TIFF files have been associated with FAX machines from the previous century. 
Perhaps you can advise as to what application you have for such multiple page TIFF files!?!?
