Caution: Exceeding the absolute maximum ratings shown in table 23.1 can permanently destroy
the chip.*
Note: * FV_PP must not exceed 13 V and V_PP must not exceed 13.5 V, including allowances for peak
overshoot. For the dual-power-supply F-ZTAT version, MD₁ must not exceed 13 V, including
an allowance for peak overshoot.
