The DLX3X character is.9 mm (.3") high. The DLX3X character is. mm (.68") high. The built-in 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 feet (DLX3X) or 3 feet (DLX3X). They require a single -volt power supply and parallel ASCII input. Important: Refer to Appnote 8, Using and Handling Intelligent Display Devices at Since this is a CMOS device, normal precautions should be taken to avoid static damage. 6--3

7 DLX3X, DLX3X Lamp Test When the lamp test (LT) is activated, all dots on the display are illuminated at brightness. The lamp test function is independent of write (WR) and the settings of the blanking inputs (BL, BL). 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. Dimming and Blanking the Display Brightness Level BL BL Blank Brightness Brightness Full Brightness 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 (T W ) 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 BL or BL should be held high for display to light up.
