? Applies for transient or continuous overvoltages applied to (+) INPUT HI (pin 11) with (–)
INPUT LO (pin 12) properly connected. Pin 12 is not overvoltage protected (see Figure 1).
Voltages applied to pin 12 should not exceed the supply voltage.
? See Technical Notes.
? BCD outputs are optional and must be speci?ed in the part number.
See Ordering Information.
? Includes high-intensity and BCD-output models.

3. DISPLAY TEST (Pin 2) : Connecting pin 2 to ground (pin 3, 5V
RETURN) will activate all LED segments, and the display will read
“–18888” regardless of the actual applied input. To reduce self-heat-
ing, the display should not be left in the “test” mode for more than 10
seconds. This pin should be left open if unused.
