Description

HVO1 -

HVO20

Driver output pin, applicable to each bit of shift register.

VHV Power supply pin for driver circuit.

GND

GND pin for the driver circuit.

GND pin for the logic circuit.

Clear input pin with pull-up resistor. Normally "H" level. In this

CL

condition, the driver outputs "H" or "L" according to the

corresponding latch output level. Setting this pin to "L" enables

the driver output to be fixed at "L" irrespective of 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

LS latch circuit.

When LS is "L", the latch circuit holds the contents of the shift

register that are immediately before LS goes "L".

DIN

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

Display data is input in synchronization with clock. (Positive Logic)

VCC

DOUT

Power supply pin for logic (except driver).

VCC should be 4.5V to 5.5V.

Serial output pin for shift register.

CLK

Clock input pin. 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"

CHG in this condition, the driver outputs "H" or "L" according to the

corresponding latch output.

Note: Pin numbers shown are for 32-pin plastic SSOP.
