OHG • Regensburg, Germany www.osram-os.com • +49-941-202-7178 2 May 31, 2000-12 Packaging Packaging consists of a transfer molded nylon lens which also serves as an “encapsulation shell” since it covers five of the six “faces.” The assembled and tested substrate (“PTF” multi- layer), is placed within the shell and the entire assembly is then filled with a water clear IC grade epoxy. This yields a very rugged part, which is quite impervious to moisture, shock and vibration. Although not “hermetic,” the device will easily withstand total immersion in water/detergent solutions.

Electrical inputs to the 3416 VCC Positive supply +5 volts GND Ground D0-D6 Data Lines The seven data input lines are designed to accept the first 64 ASCII characters. See Fig- ure 3 for DL3416 character set (The DL3416 interprets all undefined codes as a blank). See Figure 3 for DLX3416 character set. A0, A1 Address Lines The address determines the digit position to which the data will be written. Address order is right to left for positive-true logic. WR Write (Active Low) Data and address to be loaded must be present and stable before and after the trailing edge of write. (See DL3416, DLX3416 data sheets for timing information). CE1, CE2 Chip Enable (Active High) CE3, CE4 Chip Enable (Active Low) Determines which device in an array will actu- ally accept data. When either or both chip enable is in the high state, all inputs are inhibited. CLR Clear (Active Low) The data RAM and cursor RAM of the DL 3416 will be cleared when held low for 15 mS. The minimum for the CLR is 1 mS for the DLX3416. CUE Cursor Enable Activates Cursor function. Cursor will not be displayed regardless of cursor memory con- tents when cue is Low. CU Cursor Select (Active Low) This input must be held high to store data in data memory and low to store data into the cursor memory. BL Display Blank (Active Low) Blanking the entire display may be accom- plished by holding the BL input low—not a stored function. When BL is released, the stored characters are again displayed. BL can be used for flashing or dimming. |
