HANDLING

Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe, it is

desirable to take normal precautions appropriate to handling MOS devices.

All pins are compatible with “EIA/JESD22-A114-A Class1 (October 1997)”.

LATCH-UP

Pins S_DATA, TXA and TXB are susceptible to latch-up if a negative current greater than 20 mA is drawn from the

respective pin (occurs when the pin voltage is negative with respect to GND).

To avoid latch-up, pins TXA and TXB pins must be connected to VCC through coils, and the S_DATA control signal input

from the baseband IC must be kept positive with respect to GND.
