DLO4135/7135/DLG4137/7137
DESCRIPTION
The DLX413X/DLX713X are single digit 5x7 dot matrix
Intelligent Display devices. The DLX413X character is
0.43" high. The DLX713X character is 0.68" high. The built-
in CMOS integrated circuit contains memory, ASCII char-
acter generator, LED multiplexing and drive circuitry;
thereby eliminating the need for additional circuitry. They
will display the 96 ASCII characters.
These devices are TTL and microprocessor compatible
and offer the possibility of cascading the displays, allowing
for multi-character messages. These displays were
designed for viewing distances of up to 20 feet(DLX413X)
or 30 feet (DLX713X). They require a single 5-volt power
supply and parallel ASCII input.
All products are 100% tested, then subjected to out-going
AQLs of .25% for brightness matching, visual alignment
and dimensions, .065% for electrical and functional.
Important:
Refer to Appnote 18, “Using and Handling
Intelligent Displays.” Since this is a CMOS device, normal
precautions should be taken to avoid static damage.

Notes
1. “Off Axis Viewing Angle” definition: The minimum angle in any direction from the normal to the display surface at which any part of any dot
in the display is not visible.
2.
This display contains a CMOS integrated circuit. Normal CMOS handling precautions should be taken to avoid damage due to high
static voltages or electric fields. See Appnote 18.
3. Unused inputs must be tied to an appropriate logic voltage level (either V + or GND).
