This is still a bad claim. A resistor limits current and nothing else. Ignoring that will harm the rest of the circuit. > Any excess voltage is shunted by diodes inside the 74HC244 to its > 3.3V power rail. Umm, it could just break the IC. Please have a look at the data sheet again to confirm my fears. Going beyond absolute maximum ratings is not a good idea. Please avoid such recommendations. //Peter -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
