Precedence: bulk

Section 7.6 of the 2001 LRM states:

    7.6 Bidirectional pass switches

    The bidirectional pass switches shall not delay signals propagating
    through them. ...

    The delay specifications for tranif1, tranif0, rtranif1, and rtranif0
    devices shall be zero, one, or two delays. ...

First it says that there is no delay. Then the next paragraph goes into a
discussion of delays. How can the switches not delay signals if delays are
specified?

Paul
