Overview
The MC100LVEL11DG, produced by onsemi, is a 3.3V ECL (Emitter-Coupled Logic) 1:2 differential fanout buffer. 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 MC100LVEL11DG includes 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.
