These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1)
All outputs can be controlled by serial interface, except VTCXO, PAVREF1, PAVREF2 and PAVREF3.
(2)
When the PA_VDD has load current, the maximum load current of V11_V28TX is decreased from 130 mA by the value of IOUT of
PA_VDD.
(3)
When the V_LNA_FEM has load current, the maximum load current of V12_V28RX is decreased from 95 mA by the value of IOUT of
V_LNA_FEM.
