3.3V DUAL DIFFERENTIAL
LVPECL-to-LVTTL
TRANSLATOR
1
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.
10ELT is compatible with positive ECL 10H logic levels,
while the 100ELT is compatible with positive ECL 100K
logic levels.
