I've been reading through datasheets for various digital buffers and inverters. Few list "Symmetrical Output Impedance" as a feature. Here are a couple sheets that mention this:
**broken link removed**
On-Semi MC74HC1GU04
I was wondering if anyone can go into the specifics of this feature since I can't find anything about it anywhere. I need to interface some logic into an analog system, so I need fine control over the output impedance. I was going to try some devices with Open-Drain outputs, but that only lets you control the high-level output impedance and not the low. This "symmetrical" thing sounds interesting... Can someone explain it?
