s ESD protection of 2000V
s Available in 8-pin SOIC package
DESCRIPTION
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 tranlation 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.
