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.
