100LVEL11
3.3V ECL 1:2 Differential Fanout Buffer
General Description
The 100LVEL11 is a low voltage 1:2 differential fanout
buffer. One differential input signal is fanned out to two
identical differential outputs. By supplying a constant refer-
ence level to one input pin a single ended input condition is
created.
With inputs Open or both inputs at V
EE
, the differential Q
outputs default LOW and Q outputs default HIGH.
The 100 series is temperature compensated.

Absolute Maximum Ratings
(Note 1)
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.

. V
IHCMR
maximum varies 1-to-1 with V

. The V
IHCMR
range is referenced to the most positive side of the
differential input signal. Normal operation is obtained if the HIGH level falls within the specified range and the peak-to-peak voltage lies between V
PPMIN
and
1V.
Note 5: Absolute value of the input HIGH and LOW current should not exceed the absolute value of the stated Min or Max specification.
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.
