Many years ago, a non-EE colleague was very amused to see my Texas TTL databook[1] open at the 'bi-directional bus drivers' page. [1] <sing> Oh the yellow[2] rows of Texas are the data books for me! [2] Ok, at the time they were browny orange. Cheers -- Syd

That was a long time ago. the way some are drawn now you cano't tell a frasenstat from a thinamajig. Like this : http://www.edn.com/electronics-blogs/serious-fun/4427471/Funniest-schematic-ever

Those aren't so good when your circuit needs to run on a battery; they don't work without higher power. Matt Roberds
