I am after an 8:1 multiplexer IC (in fact I have 6 inputs to route to 1
output) and the 74HC151 would be ideal, except its propogation delay is too
long (33ns over -40 to 85degC) in this particular case. The inputs are TTL
but outputs of 3.3V would be fine, so I hoped there would be an equivalent
part in the LCX family for faster propogation (20ns max is what we need).
However, the 74xx151 seems only available in HC and HCT.
Is there another 8:1 multiplexer IC available, or can another logic IC (e.g.
a quad 2-input multiplexer) be connected in such a way to form an 8:1
multiplexer? I 've noticed a lot more quade 2-input multiplexers available
and they are also found in LCX family, unlike the 74xx151.
