Because low voltage positive ECL (LVPECL) levels are
used, only +3.3V and ground are required. The small
outline 8-pin SOIC package and low-skew, single-gate
design make the EPT21L ideal for applications that
require the translation of a clock or data signal where
minimal space, low power, and low cost are critical.
