TDA5051
Data format
TRANSMISSION MODE
The data input (DATA_IN) is active LOW: this means that a
burst is generated on the line (pin TX_OUT) when
pin DATA_IN is LOW.
Pin TX_OUT is in high-impedance state as long as the
device is not transmitting. Successive logic 1s are treated
in a NRZ mode (see pulse shape description in
Figs 8 and 9).
RECEIVING MODE
The data output (pin DATA_OUT) is active LOW; this means
that the data output is LOW when a burst is received.
Pin DATA_OUT remains LOW as long as a burst is received.
Power-down mode
Power-down input (pin PD) is active HIGH; this means that
the power consumption is minimal when pin PD is HIGH.
All functions, except clock generation, are disabled then.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).

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.
