Overview
The MC10EL16DTR2 is a 5.0 V ECL (Emitter-Coupled Logic) differential receiver produced by onsemi. This device is functionally equivalent to the E116 device but offers higher performance capabilities, making it ideal for interfacing with high-frequency sources. The MC10EL16DTR2 features faster output transition times compared to the E116, which is crucial for applications requiring high-speed data transmission.
The device includes an internally generated voltage supply (VBB) that can be used as a switching reference voltage for single-ended input conditions or to rebias AC coupled inputs. It also includes internal input clamps that force the Q output LOW under open input conditions.
