Figure 3. Eight-Resistor SIP Schematic

You can install the SIP as either pull-up or pull-down. At each location there are 10 holes in a line. One end of

the line is +5V, the other end is GND. They are marked HI and LO respectively. The eight holes in the middle

are connected to the eight lines of a port.

 For a pull-up function per port, mount the SIP with the common pin (marked with a dot or line) in the HI

position.

 For a pull-down function per port, mount the SIP with the common pin in the LO position.

When installing pull-up and pull-down resistor SIP packs, we recommend using a 2.2 K, eight-resistor SIP

(MCC part number SP-K2.29C). You can substitute individual 2.2 kΩ resistors for the resistor SIPs, if required.
