The MC100LVELT22DG is a dual LVTTL/LVCMOS to differential LVPECL Translator because LVPECL (low voltage positive ECL) levels are used, only 3.3V and ground are required. It is ideal for applications which require the translation of a clock and a data signal.

The 100 series Contains temperature compensation
When unused TTL input is left open, q output will default high
