Recommended Operating
Conditions
Note 1:
The
“
Absolute Maximum Ratings
”
are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum rating.
The
“
Recommended Operating Conditions
”
table will define the conditions
for actual device operation.
PECL DC Electrical Characteristics

Note 2:
V
IH
and V

values vary 1 to 1 with V
CC
. V
CC
can vary

0.25V.
Note 3:
V
IHCMR
minimum varies 1 to 1 with GND. V
IHCMR
maximum varies 1 to 1 with V
CC
.
Note:
Devices are designed to meet the DC specifications after thermal equilibrium has been established. Circuit is tested with air flow greater than
500LFPM maintained.
TTL DC Electrical Characteristics
V
CC
=
5.0V; GND
=
0.0V (Note 4)
Note 4:
V
CC
can vary
±
0.25V.
Note 5:
For I
OS
, the use of high-speed test apparatus and/or sample-and-hold techniques are preferable in order to minimize internal chip heating and more
accurately reflect operational values. Otherwise, prolonged shorting of a HIGH output may raise the chip temperature well above normal and thereby cause
invalid readings in other parameter tests. In any sequence of parameter tests, I
OS
tests should be performed last.
Note:
Devices are designed to meet the DC specifications after thermal equilibrium has been established. Circuit is tested with air flow greater than
500LFPM maintained.
