Overview
The MC10ELT25DTR2, produced by onsemi, is a differential ECL (Emitter-Coupled Logic) to TTL (Transistor-Transistor Logic) translator. This device is designed to convert ECL signal levels to TTL compatible levels, making it a crucial component in mixed-signal systems that require communication between different logic families.
The MC10ELT25DTR2 operates with a +5 V positive supply, a -5.2 V (or -4.5 V) negative supply, and a ground connection. It is available in an 8-lead SOIC and TSSOP packages, making it versatile for various board designs.
