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
a
O
e
outputs.

Note 3: F100K 300 Series cold temperature testing is performed by temperature soaking (to guarantee junction temperature equals -55°C), then testing immediately
without allowing for the junction temperature to stabilize due to heat dissipation after power-up. This provides "cold start" specs which can be considered a worst case
condition at cold temperatures.
Note 4: Screen tested 100% on each device at -55°C, +25°C, and +125°C, Subgroups 1, 2, 3, 7, and 8.
Note 5: Sample tested (Method 5005, Table I) on each manufactured lot at -55°C, +25°C, and +125°C, Subgroups A1, 2, 3, 7, and 8.
