Description

The DLR/DLO/DLG2416 is a four digit 5 x 7 dot matrix display module with a built-in CMOS integrated circuit.This dis-

play is X/Y stackable.

The integrated circuit contains memory, ASCII ROM decoder, multiplexing circuitry and drivers. Data entry is asyn-

chronous and can be random. A display system can be built using any number of DLX2416s since each digit can be

addressed independently and will continue to display the character last stored until replaced by another.

System interconnection is very straightforward. The least significant two address bits (A0, A1) are normally connected

to the like-named inputs of all displays in the system. With two chip enables (

CE1 and CE2) four displays (16 charac-

ters) can easily be interconnected without a decoder.

Data lines are connected to all DLX2416s directly and in parallel, as is the write line (WR). The display will then

behave as a write-only memory.

The cursor function causes all dots of a digit position to illuminate at half brightness. The cursor is not a character, and

when removed the previously displayed character will reappear.

The DLX2416 has several features superior to competitive devices. True ’’blanking“ allows the designer to dim the dis-

play for more flexibility of display presentation. Finally the CLR clear function will clear the cursor RAM and the ASCII

character RAM simultaneously.

The character set consists of 128 special ASCII characters for English, German, Italian, Swedish, Danish, and Norwe-

gian.

All products are subjected to out-going AQL’s of 0.25% for brightness matching, visual alignment and dimensions,

0.065% for electrical and functional.

The desired data code (D0-D6) and digit address (A0, A1) must be held stable during the write cycle for storing new data. Data entry may be asynchronous and random. Digit 0 is defined as right hand digit with A1=A2=0. To clear the entire internal four-digit memory hold the clear (CLR) low for 1.0 µs.

DLR2416, DLO2416, DLG2416 Electrical and Mechanical Considerations Voltage Transient Suppression We recommend that the same power supply be used for the display and the components that interface with the display to avoid logic inputs higher than VCC. Additionally, the LEDs may cause transients in the power supply line while they change display states. The common practice is to place .
