100325
Low Power Hex ECL-to-TTL Translator
General Description
The 100325 is a hex translator for converting F100K logic
levels to TTL logic levels. Differential inputs allow each circuit
to be used as an inverting, non-inverting or differential re-
ceiver. An internal reference voltage generator provides V
BB
for single-ended operation, or for use in Schmitt trigger appli-
cations. All inputs have 50 kΩ pull-down resistors. When the
inputs are either unconnected or at the same potential the
outputs will go low.
When used in single-ended operation the apparent input
threshold of the true inputs is 20 mV to 40 mV higher (posi-
tive) than the threshold of the complementary inputs. The
V
EE
and V
TTL
power may be applied in either order.
