(1) S_DATA input (pin 4) is subject to latch-up if a negative voltage is applied. The application circuit should be designed to prevent this occurring.
(2) TXA and TXB outputs (pins 20 and 21) are subject to latch-up if a negative output voltage occurs. To prevent this happening, the application circuit should use a DC biasing arrangement
with L5 and L6 connected to VCC as shown.
