Dual LVTTL/LVCMOS to Differential LVPECL Translator MC100LVELT22
The MC100LVELT22 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. The small outline 8-lead SOIC package and the low skew, dual gate design of the LVELT22 makes it ideal for applications which require the translation of a clock and a data signal.
