Can anyone tell me what a 958_2P is? I've recently become the proud (and puzzled) owner of a Synclavier II keyboard which I'm trying to interface to my computer. The keyboard interface card has 16 of these babies on it. As near as I can tell, they're quad nand gates (w/open collector outputs?). Here's more info: 14 pin ceramic dip. with the following markings: .SW 958_2P 7421 (one of the packages faintly says WIAT on it as well) The big question is what are the output characteristics (i.e. drive and leakage current, etc.)? I think that the pinout is (something like): 1 1A 14 Vcc 2 1B 13 4B 3 1Y 12 4A 4 2Y 11 4Y 5 2A 10 3Y 6 2B 9 3B 7 GND 8 3A Thanks!
