Summary: question on pullups

Question:  Would not having pullups on some of the unused inputs to a buffer
           chip cause the malfunction of the other buffers on the same chip?


I'm using a 74LS244 chip.  It's a low power schoktty tri-state octal driver
chip.  I'm only using 4 buffers on the chip and the other 4 are unused.
Will having the inputs to the unused buffers floating cause the other
buffers to sometimes have wrong output signals???


thanks in advance......
