Overview
The onsemi MC100LVELT22DG is a dual LVTTL/LVCMOS to differential LVPECL translator. This component is designed to translate logic levels from LVTTL (Low Voltage Transistor-Transistor Logic) or LVCMOS (Low Voltage Complementary Metal-Oxide-Semiconductor) to LVPECL (Low Voltage Positive Emitter-Coupled Logic). The device is particularly useful in applications requiring the translation of clock and/or data signals between different logic families.
