Overview
The MC100LVEL16DTR2 is a 3.3V ECL (Emitter-Coupled Logic) differential receiver produced by onsemi. This device is functionally equivalent to the EL16 but operates from a 3.3V supply, making it suitable for high-frequency applications. It features internal input pulldown resistors and is designed to interface with high-frequency sources, offering high bandwidth output transitions and low propagation delays.
