100314
Low Power Quint Differential Line Receiver
General Description
The 100314 is a monolithic quint differential line receiver with
emitter-follower outputs. An internal reference supply (V
BB
)
is available for single-ended reception. When used in
single-ended operation the apparent input threshold of the
true inputs is 25 mV to 30 mV higher (positive) than the
threshold of the complementary inputs. Unlike other F100K
ECL devices, the inputs do not have input pull-down resis-
tors.
Active current sources provide common-mode rejection of
1.0V in either the positive or negative direction. A defined
output state exists if both inverting and non-inverting inputs
are at the same potential between V
EE
and V
CC
. The defined
state is logic HIGH on the O

e
outputs.
