ECL circuits typically have relatively small logic spans of approximately 800 mV. Because of the small span, to drive TTL circuits from ECL levels normally entails the use of level converters, such as ...
The three main logic families in the 1980s were TTL, ECL, and CMOS. The three main logic families in the 1980s were TTL, ECL, and CMOS. In my previous column, we started our look at logic data sheets ...
