LVCMOS/LVTTL interface levels.
An external fixed precision resistor (475) from this pin to ground
provides a reference current used for the differential current-mode QX,
nQX outputs.
Differential output pair C. HCSL interface levels.
Differential output pair D. HCSL interface levels.
NOTE: Pullup and Pulldown refer to internal input resistors. See Table 2, Pin Characteristics, for typical values.
