Driver Invert.
Driver Term Voltage Reference.
Driver Low Voltage Reference.
Driver High Voltage Reference.
Low Clamp.
High Clamp.
Comparator Low Leakage Mode.
Determines Whether LD Responds to DR_EN_1 or is Disabled (see Table 4).
Low Speed Control Signal. When high, DR_EN_1 forces driver output to VIT. Otherwise, DR_EN_1
forces driver to High Impedance (see Table 4).
Negative Power Supply.

DR_DATA_P_1
DR_DATA_P_T_1
High Speed Data Inputs. Sets high/low state of driver output (see Table 4).
Termination Resistors for HS Inputs. Opposite end of each 50 Ω termination resistor goes to the
appropriate signal.
Termination Resistors for HS Inputs. Opposite end of each 50 Ω termination resistor goes to the
appropriate signal.
Complement of DR_DATA_P_1.
High Speed Enable Inputs. Multifunction depending on status of VTEN_1 and LDEN_1. Causes driver
to enter/leave inhibit; driver to enter/leave termination mode; load to leave/enter inhibit (see
Table
4).
Termination Resistors for HS Inputs. Opposite end of each 50 Ω termination resistor goes to the
appropriate signal.
Termination Resistors for HS Inputs. Opposite end of each 50 Ω termination resistor goes to the
appropriate signal.
Complement of DR_EN_P_1.
No Connect.
High Comparator Outputs.
Complement of COMP_H_P_1.
