Differential digital inputs. The output will toggle between the two levels dictated by
V
H
and V
L
as the differential signal is switched. Although these inputs will normally
be driven by ECL signals, they have a wide enough common mode range that any
one of the inputs may be driven by a TTL or CMOS signal provided that the other
input is tied to the appropriate threshold voltage.
