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.
