DESCRIPTION
The SY10/100ELT23L are dual differential LVPECL-
to-LVTTL translators with +3.3V power supply. Because
LVPECL (Low Voltage Positive ECL) levels are used,
only +3.3V and ground are required. The small outline 8-
lead SOIC package and the low skew, dual gate design
of the ELT23L makes it ideal for applications which
require the translation of a clock and a data signal.
The ELT23L 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.
