1: Processing of redundant unused input pins In most cases, not all pins of integrated circuit chips will be used. For example, the 74ABT16244 series devices can use up to 16 I/O pins, but in fact, no...
[size=4]I tried connecting the IO port directly to the base of the NPN transistor (without connecting a resistor in series with the base). The push-pull output drove the transistor to work in a switch...
