Overview
The MC100EP11DR2GH 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, making it ideal for applications requiring high-speed signal processing. The MC100EP11 includes temperature compensation, which is a key feature of the 100 Series.
