MC100ELT25DR2

The MC100ELT25DR2 from ON Semiconductor is a differential ECL to TTL translator designed for applications requiring high performance and low power consumption in a compact form factor. This translator operates using ECL logic levels and requires a +5V, -5.2V (or -4.5V) power supply along with ground.

Key electrical characteristics include a typical propagation delay of 2.6ns and TTL outputs capable of sourcing or sinking 24mA. The device features internal input resistors, with pulldown resistors on the D inputs and both pulldown and pullup resistors on the D inputs. The Q output defaults to LOW when inputs are open or at VEE. The MC10ELT/100ELT25 series is available in both ECL standards, with the 10ELT compatible with MECL 10H logic levels and the 100ELT compatible with ECL 100K logic levels.

Packaged in a small outline SOIC package, the MC100ELT25DR2 is suitable for space-constrained designs. The VBB output allows for single-ended input operation when tied to the IN input, either for non-inverting or inverting buffer configurations. If the VBB pin is used, it should be bypassed to ground with a 0.01 µF capacitor. The component has a transistor count of 135 devices and is manufactured using the MOSAIC 1.5 process, contributing to its cost-effectiveness.
