7.5 Break-Before-Make

Break-before-make delay is a safety feature that prevents two inputs from connecting when the device is

switching. The output first breaks from the on-state switch before making the connection with the next on-state

switch. The time delay between the break and the make is known as break-before-make delay. Figure 11 shows

7.6 Charge Injection

The TMUX1237 has a transmission-gate topology. Any mismatch in capacitance between the NMOS and PMOS

transistors results in a charge injected into the drain or source during the falling or rising edge of the gate signal.

The amount of charge injected into the source or drain of the device is known as charge injection, and is denoted
