Note 1:
Conditions for testing, not shown in the Table, are chosen to guarantee operation under ‘‘worst case’’ conditions.
Note 2:
The specified limits represent the ‘‘worst case’’ value for the parameter. Since these ‘‘worst case’’ values normally occur at the temperature and supply
voltage extremes, additional noise immunity and guard banding can be achieved by decreasing the allowable system operating ranges.
Note 3:
Typical limits are at V

Note 4:
The M
1
and M
2
threshold specifications are normally referenced to the V
CC
potential, as shown in the ECL operation tables. Using V
EE
(GND) as the
reference, as in normal TTL practice, effectively makes the threshold vary directly with V
CC
. Threshold is typically 1.3V below V
CC
(e.g.,
a
3.7V at V
CC
e a
5V). A
signal swing about threshold of
g
0.4V is adequate, which gives the state V
IH
and V
IL
values. The internal 2 k
X
resistors are intended to pull TTL outputs up to the
required V
IH
range, as discussed in the Functional Description and shown in Figure 5.
Note 5:
TTL Output Signal swing is guaranteed at f
MAX
over temperature range.
Note 6:
M
1
or M
2
can be tied to V
CC
for fixed divide-by-ten operation.
