In the early digital era, logic gates were made exclusively of transistors and discrete components. The obvious occupation of a large space and increased heat dissipation pushed technology to ...

A modification to the DprobeXC in-circuit emulator enables engineers to record external transistor-transistor logic (TTL) signals, a requirement for testing integration for XC166 applications, says ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...
