Note 1:
In B mode, you must use a low duty cycle (D%
 10%) due to the IC power dissipation limit.
2:
In CW mode (D% = 100%), the VPP/VNN output voltage must be reduced due to the IC power dissipation
limit.
3:
When the TXCH output is in RTZ+ state, the channel is in Receiving mode (RTZ+).
4:
When the TXCH output is in high-Z state, all output MOFETs are off.
5:
When ETI = 1 (TRSW), all channels are in Receiving mode after the delay.
6:
When INV = 1, Tx0~15 are inverting the output waveforms.
