SEGR is the right hand of the two displays.

SEGL is the left hand of the two displays

If the POL pin is open or hi, this SEG outputs will be high when a segment is on.

If the POL pin is low or grounded, the SEG outputs will be low when a segment is on.

These are the eight segment outputs to each individual display SEGDP is the decimal point.

An external driver or current limiting resistor is required for each segment. If you are using only a

resistor, it must be sized to limit source current to 5 mA maximum per pin or sink current to 9 mA

per pin.

See also the segment table, and the ASCII to seven segment translation table.

VSS

Connect to system ground.

VDD

Connect to supply voltage of 2.4 to 5 volts. A .1 uF decoupling capacitor to ground is

recommended.

NOTES:

Make no connection to the NC pins. Pins 9 and 19 must be left unconnected.
