DESCRIPTION
The DLR/DLO/DLG1414 is a four digit 5x7 dot matrix display module with a
built-in CMOS integrated circuit. This display is a drop-in dot matrix replacement for the DL1414T with segmented characters.
The integrated circuit contains memory, ASCII ROM decoder, multiplex circuitry and drivers. Data entry is asynchronous and random. A display system
can be built using any number of DLX1414s since each character in any
DLX1414 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. Data lines are connected to all DLX1414s directly
and in parallel as is the write line (WR
write only memory.
The DLX1414 has several features superior to competitive devices. The
character set consists of 128 special ASCII characters for English, German,
Italian, Swedish, Danish, and Norwegian.
See Appnotes 18, 19, 22, and 23 for additional information.
