Overview
The MC100EP11DTG is a 3.3 V/5 V ECL (Emitter-Coupled Logic) 1:2 differential fanout buffer produced by onsemi. This device is part of the 100 Series, which includes temperature compensation, making it ideal for applications requiring high-speed AC performance. The MC100EP11DTG is pin and functionally equivalent to the LVEL11 device but offers significantly faster AC performance. It operates in both PECL (Positive ECL) and NECL (Negative ECL) modes, supporting a wide range of voltage supplies.
