Outputs Disabled OUTn+ = H, OUTn- = H
Non-inverted, Inverted, Differential Data Inputs internally biased to
Approximately 1.2 V.
Non-inverted, Inverted Differential Outputs.
OE0/OE1 enables OUT0/OUT1 when HIGH. When LOW, OUTx are
powered down and both OUT+ and OUT- float HIGH.
Selects Source for OUT, Selects Either IN0 (LOW) or IN1 (HIGH); defaults
HIGH when left open.
Selects Source for OUT1. Selects Either IN (HIGH) or IN0 (LOW); defaults
HIGH when left open.
Selects Source for OUT0. Selects either IN (LOW) or IN1 (HIGH); defaults
HIGH when left open.
3.3 V Positive Supply Voltage for Digital Logic.
3.3 V supply for LVPECL output drivers. VDDP is for OUT, VDDP0 is for
OUT0, and VDDP1 is for OUT1.
Negative Supply Voltage, Connected to Ground
