Overview
The MC100EPT21DG, produced by onsemi, is a 3.3V Differential LVPECL/LVDS/CML to LVTTL/LVCMOS translator. This component is designed to translate clock or data signals from LVPECL, LVDS, or CML input levels to LVTTL/LVCMOS output levels, utilizing only a +3.3V power supply and ground. The device is available in a small outline 8-lead SOIC package, making it ideal for applications requiring signal translation in compact spaces.
