100391
Low Power Single Supply Hex TTL-to-PECL Translator
General Description
The 100391 is a hex translator for converting TTL logic lev-
els to F100K PECL logic levels. The unique feature of this
translator, is the ability to do this translation using only one
+5V supply. The differential outputs allow each circuit to be
used as an inverting/non-inverting translator, or as a differ-
ential line driver. A common enable (E), when LOW, holds
all inverting outputs HIGH and all non-inverting inputs
LOW.
The 100391 is ideal for those mixed PECL/TTL applica-
tions which only have +5V supply available. When used in
the differential mode, the 100391, due to its high common
mode rejection, overcomes voltage gradients between the
TTL and PECL ground systems.
