to-LVTTL translators using a single +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 low skew single gate
design make the ELT21L ideal for applications that require
the translation of a clock or data signal where minimal
space, low power, and low cost are critical.

10ELT is compatible with positive ECL 10H logic levels,
while the 100ELT is compatible with positive ECL 100K
