Overview
The MC10EL11DR2, produced by onsemi, is a 5.0 V ECL (Emitter-Coupled Logic) 1:2 differential fanout buffer. This device is functionally similar to the E111 but offers higher performance capabilities, including improved within-device skew and propagation delay. It is designed to maintain stability under open input conditions through clamping circuitry, ensuring the Q outputs go LOW if the inputs are left open or pulled to VEE.
