Overview
The MC100LVELT22DTR2 is a dual LVTTL/LVCMOS to differential LVPECL translator produced by Onsemi. This device is designed to translate LVTTL (Low Voltage Transistor-Transistor Logic) and LVCMOS (Low Voltage Complementary Metal-Oxide-Semiconductor) signals to differential LVPECL (Low Voltage Positive Emitter-Coupled Logic) signals. The translator operates with a single +3.3V power supply and ground, making it suitable for applications requiring efficient signal translation.
