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.

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
digit 3 digit 2
digit 1 digit 0
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).

Chip Enable (Active High)
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.
