For the electronics nerds: I need to step down six 5V signals to 3.3V. I don't want to mess with a half-dozen voltage dividers; ideally this would be a single chip solution. I also don't need bidirectional or tristate support. What I do need is relatively fast propagation; 20ns would be a good target. Any recommendations?

Thanks, everyone, for all the recommendations! It looks like 74LVx244/245 is the way to go. I'd ignored the tristate buffers and was looking at 74x4050s and such, but it turns out all that silicon is old and super slow.

okay, down to the '245 and the 74LCX541 @fruchti mentioned. Quibbling about one or two ns propagation delay differences at this point.

@fruchti actually, the '541 wins on the basis of pinout: all the inputs are on one side, all the outputs on the other. Much easier to route!
