order to cascade devices the DO of one chip must be
connectedtoDlofthefollowingchip(seeFig.1).
The clock input pin (CLK) is used to clock the Dl serial data into
the 40-bit shift register. Loading, shifting and outputting of the
data occurs at the falling edge of this clock (see Fig. 3). When
cascadingdevices,allCLKlinesshouldbetiedtogether.
The strobe input pin (STR) is usedto latch the input data shifted
into the 40-bit shift register. The latched data is held for display.
A logic "1" on the STR input transfers the data contained in the
shift register cells to the corresponding latches. The latches
remain open during the whole time STR remains at logic "1".
When cascading devices the STR lines should all be con-
nected.
When R is active (high), the display is blanked: all segment
outputs are tied to V
. R does not clear the information in the
latches.

Segment Driver
The number of segment drivers available on the chip is 40.
Eachsegment drivercanbeusedas backplane-driver. Iftwo or
more drivers are connected together, care must be taken to
ensure the drivers do not cause circuit malfunction by driving
oneagainsttheother.
FR Input
This input controls the segment output switching frequency
according to Table 6. It must be connected to an external clock
signal. When cascading devices, their FR inputs may all be
connectedtoa commonsignal.
