8.5 Break-Before-Make Delay

The break-before-make delay is a safety feature of the TMUX7308F and TMUX7309F. The ON switches first

break the connection before the OFF switches make connection. The time delay between the break and the

make is known as break-before-make delay. Figure 8-6 shows the setup used to measure break-before-make

delay, denoted by the symbol tBBM.
