PIN DESCRIPTION
Pin Name
I/O
Description
Clock Input Pin
CLK
I This pin reads serial data at the rising edge and
outputs data at the falling edge.
Serial Interface Strobe Pin
STB
I
The data input after the STB has fallen is
processed as a command. When this in is
“HIGH”, CLK is ignored.
K1 to K2
Key Data Input Pins
I The data inputted to these pins is latched at the
end of the display cycle.
VSS
- Logic Ground Pin
VDD
- Logic Power Supply
SG1/KS1 to SG8/KS8
O
High-Voltage Segment Output Pins
Also acts as the Key Source.
VEE
- Pull-Down Level
SG9/GR8 to SG12/GR5 O High-Voltage Segment Output Pins
GR4 to GR1
O High-Voltage Grid Output Pins
OSC
Oscillator Input Pin
I A resistor is connected to this pin to determine
the oscillation frequency.
DOUT
Data Output Pin (N-Channel, Open-Drain)
O This pin outputs serial data at the falling edge of
the shift clock (starting from the lower bit).
Data Input Pin
DIN
I This pin inputs serial data at the rising edge of
the shift clock (starting from the lower bit).
Pin No.
