I have 8 CMOS chips running from 5VDC. Normally I would use a 4.7k ohm resistor for a pull-up. However in this configuration these 8 chips all have their not LT pins tied together. I am going to run these to a pull-up connected to the positive rail, and to a button connected to the negative rail. Since there are 8 chips, I'm not sure what to do about the pull-up resistor. For pins like LT, I don't think the datasheet states current for operation. So where do I begin?
Thank you
