ONSEMI MC100ELT22

SEMICONDUCTOR TECHNICAL DATA
The MC10ELT/100ELT22 is a dual 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 low skew, dual
gate design of the ELT22 makes it ideal for applications which require the
translation of a clock and a data signal. Because the mature MOSAIC 1.5
process is used, low cost can be added to the list of features.
The ELT22 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.
