8.3.1 Wide Input Signal Range (up to ±110 V, 220 VPP)

TMUX9616 can pass a wide input signal range, up to VDD/VSS of ±110 V (220 VPP), which is very beneficial as many high voltage transmitters are designed to transmit up to ±100 V. The extra headroom above ±100 V that TMUX9616 provides is critical for operating the high voltage transmitters in systems up to ±100 V for a few reasons. First, with high voltage supply multiplexers (±110 V VDD/VSS), typically as the VS pin approaches VDD (VS > VDD - (5 V to 10 V)), the RON of the switch starts to rapidly increase. With a large change in RON when VS is near VDD, this can cause the harmonic distortion performance of the system to degrade (HD2PC, so fourth). Setting the high voltage supplies 10 V above the pulser operating voltage, allows VS to stay ≤ (VDD - 10 V), keeping the switch in its flat RON operating region for the intended TX signal, and therefore greatly improving system harmonic distortion performance.

Second, various system parasitics (or even intentionally added tuning inductors) and transmission line reflections in the system (due to cables, long PCB traces, and so forth) can cause some temporary peaking of the maximum voltage that the TMUX9616 receives above the ±100 V maximum output voltage of the high voltage transmitter. Having the high voltage multiplexer in the system have voltage tolerance above the high voltage transmitter (up to VDD = +110 V and VSS = -110 V per Recommended Operating Conditions) is crucial for being able to run the system at the high voltage transmitters maximum voltage output capability.
