74LS244 et al.1. 74ls series haven't z-state for TTL, only "0" or"1". On the not connected input you have 1 (for ls series).

I think the TS meant, that they don't have a way of detecting a Hi-Z output connected to the probe. You can do it, but it takes some work an ingenuity.74LS244 et al.
I know. I mean that 74ls00 and 74als00 don't have an undefined state, and they can't show no signal at the input. Only 1 or 0.74LS244 et al.
