The transistor turnson, and the logic-zero voltage at thecollector is approximately 0.6+V L +V CE,where V L is the low voltage and V CE is the collector-to-emitter voltage.When inputs A and B are at ...

DTL stands for diode-transistor logic and it was popular in “930-series” logic devices. I used wire-wrap or point-to-point solder-connection breadboards. But they became a pain when I needed to modify ...
