Overview
The MC100LVELT22DTRG 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. It operates with a single +3.3V power supply and is housed in an 8-lead TSSOP package, making it suitable for applications requiring clock and data signal translation.
