Description
The 20 mm (0.8 inch) LED seven
segment displays are designed
for viewing distances up to 10
metres (33 feet). These devices
use an industry standard size
package and pinout. All devices
are available as either common
anode or common cathode.
HDSP-340X Series
HDSP-390X Series
HDSP-420X Series
HDSP-860X Series
HDSP-N15X Series
These displays are ideal for most
applications. Pin for pin
equivalent displays are also
available in a low current design.
The low current displays are ideal
for portable applications. For
additional information see the
Low Current Seven Segment
Displays data sheet.

Notes:
1. These displays are recommended for high ambient light operation. Please refer to the HDSP-N10X AlGaAs data sheet for low
current operation.
2. Universal pinout brings the anode and cathode of each segment's LED out to separate pins. See internal diagram E.
