TMUX1308-Q1: 5V Timing Specs

Part Number: TMUX1308-Q1

Tool/software:

Hello,

My customer has the following questions after reviewing the datasheet:

First question: Total time from one channel to another is t = t_break_before_make + t_transition + t_propagation_delay. Is this correct?

Second, The break before make does not have max specs at -40 to 125C. How should this be characterized? 

Thanks,

Alberto
