Bonjour,
je viens de tomber sur se terme standard TTL logic level et je ne trouve pas son sense sur google ,
Le contexte :
A typical 80x86 system component uses standard TTL logic levels. This means each
wire on a bus uses a standard voltage level to represent zero and one1. We will always
specify zero and one rather than the electrical levels because these levels vary on different
processors (especially laptops).
