Alphanumeric Intelligent Display® Devices With Memory/Decoder/Driver

The DLR3416, DLO3416, DLG3416 is a four character 5 x 7 dot matrix Display module with a built-in CMOS integrated circuit. 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 DLX3416s 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 four chip enables, four Displays (16 characters) CAN easily be interconnected without a decoder. Data lines are connected to all DLX3416s directly and in parallel, as is the write line (WR). The Display will then behave as a write-only memory. By Osram Opto Semiconductors
