100325 Low Power Hex ECL-to-TTL Translator
100325
Low Power Hex ECL-to-TTL Translator
General Description
The 1003 25 is a he x translator f or convert ing F100K logic
levels to TTL lo gic levels. Differ ential in puts a llow each c ir-
cuit to be used as an inverting, no n-inverti ng or differential
receiver. An internal reference voltage generator provides
V
BB
for single-ended operation, or for use in Schmitt trigger
applications. All inputs have 50k
Ω 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 20mV to 40mV higher (posi-
tive) than the threshold of the complementary inputs. The
V
EE
and V
TTL
power may be applied in either order.
