Available in 8-pin SOIC package
The SY10/100ELT23 are dual differential PECL-to-TTL
translators. 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 ELT23 makes it ideal for applications which require
the translation of a clock and a data signal.
The ELT23 is available in both ECL standards: the
10ELT is compatible with positive ECL 10H logic levels,
while the 100ELT is compatible with positive ECL 100K
logic levels.

implied at conditions other than those detailed in the operational sections
of this data sheet. Exposure to ABSOLUTE MAXIMUM RATlNG conditions
for extended periods may affect device reliability.
