ON MC100ELT28 Ttl to differential pecl/differential pecl to ttl translator Datasheet

SEMICONDUCTOR TECHNICAL DATA
The MC10ELT/100ELT28 is a differential PECL to TTL translator and a
TTL to differential PECL translator in a single package. Because PECL
(Positive ECL) levels are used only +5V and ground are required. The
small outline 8-lead SOIC package and the dual translation design of the
ELT28 makes it ideal for applications which are sending and receiving
signals across a backplane. Because the mature MOSAIC 1.5 process is
used, low cost can be added to the list of features.
The ELT28 is available in both ECL standards: the 10ELT is compatible
with positive MECL 10H logic levels while the 100ELT is compatible with
positive ECL 100K logic levels.
