43/68 Single Character DLO4135/7 5x7 Dot Matrix Intelligent Display® with Memory/Decoder/Driver

Infineon Technologies 

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).

4. VCC=5.0 VDC ± 10%.

5. Clean only in water, isopropyl alcohol, freon TF, TE (or equivalent).
