Overview
The MC100LVEL11 is a 3.3V ECL (Emitter-Coupled Logic) 1:2 differential fanout buffer produced by onsemi. This device is functionally similar to the E111 but offers higher performance capabilities, making it ideal for applications requiring superior AC performance. It features improved within-device skews and output transition times compared to its predecessor. The MC100LVEL11 includes differential inputs with clamping circuitry to maintain stability under open input conditions, ensuring the Q outputs default to LOW if the inputs are left open or pulled to VEE.
