Overview
The MC10ELT25DTR2G, produced by onsemi, is a differential ECL (Emitter-Coupled Logic) to TTL (Transistor-Transistor Logic) translator. This device is designed for applications where space, performance, and low power consumption are critical. It operates with ECL levels, requiring a +5 V, −5.2 V (or −4.5 V), and ground supply. The MC10ELT25DTR2G is packaged in an 8-lead SOIC (Small Outline Integrated Circuit) and is ideal for high-speed translation between ECL and TTL logic systems.
