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 builtin CMOS integrated circuit contains memory, ASCII character 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).

When the lamp test (LT) is activated, all dots on the display
are illuminated at 1⁄7 brightness. The lamp test function is
independent of write (WR) and the settings of the blanking
inputs (BL0, BL1).

This convenient test gives a visual indication that all dots are
functioning properly. Lamp test also may be used as a cursor
function or pointer which does not destroy previously displayed characters.

Loading Data
Loading data into the display is straightforward. Chip enable
(CE) should be present and stable during a write pulse (WR).
Parallel data information should be stable for the minimum
time (TW) and held for TDH after write has gone high. No synchronization is necessary and each character will continue to
be displayed until it is replaced with another. Multiple displays may be stacked together with only an additional
decoder IC for chip enable decoding.
Note : Either BL0 or BL1 should be held high for display to light up.
