SEMICONDUCTOR TECHNICAL DATA
The MC10ELT/100ELT20 is a TTL to differential PECL translator.
Because PECL (Positive ECL) levels are used only +5V and ground are
required. The small outline 8-lead SOIC package and the single gate of
the ELT20 makes it ideal for those applications where space,
performance and low power are at a premium. Because the mature
MOSAIC 1.5 process is used, low cost can be added to the list of
features.
The ELT20 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.
