TAP Portugal New York to Venice with 1 h 15 min. Connection in Lisbon

I found a reasonable flight from New York to Venice with TAP Portugal with one stop in Lisbon. Nonetheless, I noticed the connection clocks in at a mere 1 hr. 15 min. Is this, perhaps too little time? This flight would put me in Venice at 12:30 in the afternoon (I only have 3 nights in Venice and I would certainly be disappointed if I had to catch a much later flight due to unforeseen delays or long lines in customs thereby missing most of the first day).
