All pins on the TMUX7308F and TMUX7309F support HBM ESD protection level up to ±3.5 kV, which helps the device from getting ESD damages during manufacturing process.

The drain pins (D or Dx) have internal ESD protection diodes to the supplies V_DD and V_SS, therefore the voltage at the drain pins must not exceed the supply voltages to prevent excessive diode current. The source pins have specialized ESD protection that allows the signal voltage to reach ±60 V regardless of supply voltage level. Exceeding ±60 V on any source input may damage the ESD protection circuitry on the device and cause the device to malfunction if the damage is excessive.
