Hi All, I have a TLC2543 ADC whose data output is CMOS and I would like to convert this to drive the TTL input pin on the parallel port. The datasheet of the TLC2543 implies that it is able to drive a TTL input but after sending the signal down a parallel port cable the data gets corrupted. I can probably use a buffer to do this but seems like a sledgehammer just for the one job. I've tried a FET transistor and this solves the problem but the data is inverted. I can correct this in software but would rather have a hardware solution. Given the many transistor types out there, is technically possible to use a simple single transistor arrangement that doesn't invert? Thanks.
