A discussion on the drive-current for the outputs of a PIC12C508A microcontroller
Each of the output lines of a ‘508A microcontroller can deliver a maximum of 25mA. What does this mean? It means any device connected to the line must take 25mA or less. If it takes more than 25mA a buffer transistor (also called an amplifying transistor) must be used and this will be discussed in a […]
