Available in 8-pin SOIC package
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.

NOTE:
1. Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS
are exceeded. This is a stress rating only and functional operation is not
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.
