FUNCTION
V_CC
V_L
V+
System power supply input (2.7V to 3.6V).
Logic power supply. Sets the V_OH of all the logic outputs and the switching point of all logic inputs. Keep V_L greater than 1.6V (1.8V
- 10%) and less than or equal to V_CC. Power up V_L after V_CC
Internally generated positive transmitter supply (typically +5.5V).
V-
Internally generated negative transmitter supply (typically -5.5V).
GND Ground connection. This is also the potential of the thermal pad (PD).
C1+
External capacitor (voltage doubler) is connected to this lead.
C1-
External capacitor (voltage doubler) is connected to this lead.
C2+
External capacitor (voltage inverter) is connected to this lead.
C2-
External capacitor (voltage inverter) is connected to this lead.
T_IN
TTL/CMOS compatible transmitter Inputs. The V_L voltage sets the input switching point.
