How do I set a Divide-By-N counter High or Low
I need to know how to set the pins on a Divide-By-N counter either High or
Low on a PCB. Also is "1" and "0" the same as high and low? Can anyone help me? |

If you mean a TTL compatible chip, 0 is ground, 1 is safest through a resistor (e.g, 1K, can share for a dozen inputs) to +5. For normal positive logic, 0 and 1 are the same as low and high. If you are just doing the PCB artwork, ask the designer to clarify. Ultimately, it's their responsibility but they'll manage to blame you if it is wrong. :) Or, are you asking something else? --- sam | Sci.Electronics.Repair FAQ Mirror: http://repairfaq.ece.drexel.edu/ Repair | Main Table of Contents: http://repairfaq.ece.drexel.edu/REPAIR/ +Lasers | Sam's Laser FAQ: http://repairfaq.ece.drexel.edu/sam/lasersam.htm | Mirror Sites: http://repairfaq.ece.drexel.edu/REPAIR/F_mirror.html Note: These links are hopefully temporary until we can sort out the excessive traffic on Repairfaq.org.
