#110138 - nice copy, where is the question Responding to: ???'s previous message |
HOw this should be taken care of while connecting the driver circuit to the port.
nice copy of the datasheet, where is the question WHAT driver circuit, what connection? could you possibly just ask yourt question. Erik |
