Overview
The MC100EP11DG is a 3.3 V / 5 V ECL (Emitter-Coupled Logic) 1:2 differential fanout buffer produced by onsemi. This device is pin and functionally equivalent to the LVEL11 device but offers significantly faster AC performance. It is part of the 100 Series, which includes temperature compensation, making it ideal for applications requiring high-speed signal processing.
