Comparison between the performance parameters of Tristate buffer and Schmitt Trigger

Question

I want to know the comparison between the performance parameters of Tristate buffer and Schmitt Trigger. By performance parameters, I mean things like propagation delay,power consumption etc.

Thank you

Edit

I want to know, for example, if I use tri-state buffer as a repeater in a simple circuit, will it make propagation delay less than that if I use schmitt trigger as a repeater in that same circuit ? If so then why ?

Answer 1

If strongly driven with fast edges, your choice of delay comes down to technology and # internal inverters.

Again, you want small geometry CMOS, with just one or 2 stages on Inverters. Examine the delays of non-inverting TriStage buffers; the TriState circuit is merely an Inverter with extra FETS, to enable or disable; to maintain data polarity, at least one more inverter is needed.
