Description
V
HV
Driver output pin, applicable to each bit of shift register
Power supply pin for driver circuit
GND 1
GND pin for the logic circuit (excluding driver circuit)
GND1 and GND2 are not connected inside of the IC.
23
38
GND 2
GND pin for driver circuit. Connect this pin to GND2 near
the mounted IC so that GND1 and GND2 will be at
common level.
CL
24
Clear input pin with pull-up resistor. Normally "H" level.
In this condition, the driver outputs "H" or "L" according to
the corresponding latch output level. Setting to "L"
enables the driver output to be fixed at "L" without respect
to latch output.
26
LS
Latch strobe input pin with neither pull-up nor pull-down
resistor. When LS is "H", the output of the shift register
becomes that of the latch circuit. When LS is "L", the latch
circuit holds the contents of the shift register before LS
goes "L".
Shift direction control pin with a pull-up resistor.
Normally "H", and in this condition, data of bidirectional
shift register is shifted to the direction of R-40 from R-1.
When this pin is "L", bidirectional shift register shifts data
to the direction of R-1 from R-40.
28
R/
L
29
DIN
Shift register input pin with neither pull-up nor pull-down
resistor. Display data is input in synchronization with
clock. (Positive logic)
30
31
V
CC
Power supply pin for logic (except driver)
V
CC
should be 4.5V to 5.5V.
32
DOUT
Serial output of bidirectional pin shift register. When R/
L
is "H", DOUT outputs R-40's output. When R/
L
is "L",
DOUT outputs R-1's output.
34
CLK
Clock input pin with neither pull-up nor pull-down resistor.
Data of shift register is shifted from one stage to the next
at the rising edge of clock.

CHG
Test input pin with a pull-down resistor. Normally "L".
If
CL
= "H" in this condition, the driver outputs "H" or "L"
according to the corresponding latch output.
If
CL
= "H", setting CHG to "H" enables the driver output to
be fixed at "H" without respect to latch output.
