I'm building a timer with eight 74LS90's in series counting down by ten from either 100KHz or 1KHz. For some reason, the fourth digit counts 1,3,5,7,9,1...
I have several .1 bypass caps at several points on the CB across +5V and ground, but not one on each '90. Has anyone seen this strange behavior?
