Description

Driver output pin, applicable to each bit of shift register

Power supply pin for driver circuit

GND pin for driver circuit. Connect this pin to GND2 near

the mounted IC so that GND1 and GND2 will be at

common level.

GND pin for the logic circuit (excluding driver circuit)

GND1 and GND2 are not connected inside of the IC.

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.

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.

Shift register input pin with neither pull-up nor pull-down

resistor. Display data is input in synchronization with

clock. (Positive logic)

Power supply pin for logic (except driver)

VCC should be 4.5V to 5.5V.

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.

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.

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.
