Clear Memory
Clearing of the entire internal four-digit memory may be accom-
plished by holding the clear line (CLR) low for one complete
internal display multiplex cycle, 1 mS; less time may leave
some data uncleared. CLR also clears the cursor memory.
Display Blanking
Blanking the display may be accomplished by loading a blank,
space into each digit of the display or by using the (BL) display
blank input. Setting the (BL) input low does not affect the con-
tents of either data or cursor memory. A flashing display can be
realized by pulsing (BL).

Data lines
The seven data input lines are designed to
accept the first 128 ASCII characters.
See Figure 3 for 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 data sheet for
timing information).
CE1, CE2
Chip Enable (Active Low)
This determines which device in an array
will actually 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 will be
cleared when held low for a minimum of
1 mS.
CUE
Cursor Enable. Activates Cursor function.
Cursor will not be displayed regardless of
cursor memory contents 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. This
is not a stored function, however. When
BL is released, the stored characters are
again displayed. BL can be used for flash-
ing or dimming.

Packaging
Packaging consists of a nylon lens which also serves as an
“encapsulation shell” since it covers five of the six “faces.”
The assembled and tested substrate 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/deter-
gent solutions.
