Measurement Setup for Input and Output Leakage Current under Overvoltage Fault with Unpowered or Floating Supplies 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. 3 V VA 0 V tBBM 1 0.8 VS Output 0 V tBBM = min ( tBBM 1, tBBM 2) VS tBBM 2 tr < 20 ns tf < 20 ns SW S1 S2 D SW S8 GND RL GND GND SW GND Decoder A0 A1 A2 GND VA GND VS GND EN CL VEN SW S7 VDD VSS VDD VSS GND 0.1 µF GND 0.1 µF Figure 8-6.
