Description
The 14.22 mm (0.56 inch) LED
dual digit seven segment displays
use industry standard size
package and pinout. The device is
available in either common anode
or common cathode. These gray
face displays are suitable for
indoor use.
• Design flexibility
Common anode right hand deci-
mal point or common
cathode right hand decimal point
Applications
• Suitable for indoor use
• Not recommended for industrial
application, i.e., operating tem-
perature requirements exceeding
+85˚C or below –25˚C
[1]
• Extreme temperature cycling not
recommended
Note:
1. For additional details, please contact your
local Agilent sales office or an authorized
distributor.
