Post by thread:Problem with RA4 on the '71, I only get 2Vs

I have RA4 on a 4.7K pullup. When I drive the pin high I only get a voltage of 2 volts maybe 2.1. 4.7K!!! Anyway It hangs around .68mV when I am not driving it low. I really need help with this. I fall below ttl level from time to time and its killing me. It works fine if I put a 680Ohm pullup on it but then my lower voltage is horrendus(sp). I know about the screwed up tristate reg on it and I only move an image of RA into the ra reg(not the tristate I leave it alone). Help please.... later John _____________________________________________________________________________ John Johnson |If it's not OS/2.|spam_OUTjohnsonjTakeThisOuTccwf.cc.utexas.edu |It's crap! |.....johnsonjKILLspam@spam@ghostwheel.bga.com OOOO SSSS /2222 2222 11 | | O O S / 2 2 1 |"We need breath- |"Bite me."
