Overview
The MC100LVELT23DG is a 3.3 V dual differential LVPECL/LVDS to LVTTL translator produced by onsemi. This component is designed to translate signals from LVPECL (Positive ECL) or LVDS levels to LVTTL (Low Voltage Transistor-Transistor Logic) levels, utilizing only a +3.3 V power supply and ground. The device is available in an 8-lead SOIC, TSSOP, and DFN package, making it suitable for applications requiring the translation of clock and data signals.
