#39214 - DS89C420 serial loader Responding to: ???'s previous message |
What if the '125 tristate buffer is replaced with a '393 inverter? That's what I did, but only a power on reset after loading will allow my DS89C420 to run. Didn't think it about 'til now. Really.
Can /EA be allowed to float? This exact schematic is in the Dallas notes, but I thought /EA must be tied high or low? Great site. |
