FUNCTION
System power supply input (3.0V to 5.5V).
Internally generated positive transmitter supply (+5.5V).
Internally generated negative transmitter supply (-5.5V).
Ground connection. This is also the potential of the thermal pad (PD).
External capacitor (voltage doubler) is connected to this lead.

TTL/CMOS compatible transmitter Inputs. The switching point is a function of the V_L voltage.
±15kV ESD Protected, RS-232 level (nominally ±5.5V) transmitter outputs.
±15kV ESD Protected, RS-232 compatible receiver inputs.
TTL/CMOS level receiver outputs. Swings between GND and V_L.
Logic-Level Supply. All TTL/CMOS inputs and outputs are powered by this supply.
Active low TTL/CMOS input to tri-state receiver and transmitter outputs and to shut down the on-board power supply to place device
in low power mode. The switching point is a function of the V_L voltage.
No Connection
Exposed Thermal Pad. Connect to GND.
