Description
Pin No.
CLK
I
Clock Input Pin This pin reads serial data at the rising
edge and outputs data at the falling edge.
Serial Interface Strobe Pin The data input after the STB
has fallen is processed as a command. When this pin is
“HIGH”, CLK is ignored.
Key Data Input Pins The data sent to these pins are
latched at the end of the display cycle.
Logic Ground Pin
Logic Power Supply
High Voltage Segment Output Pins Also acts as the Key
Source
Pull Down Level
High Voltage Segment/Grid Output Pins
High Voltage Grid Output Pins
Oscillator Input Pin A resistor is connected to this pin to
determine the oscillation frequency.
Data Output Pin (N-Channel, Open Drain) This pin
outputs serial data at the falling edge of the shift clock
(starting from the lower bit).
Data Input Pin This pin inputs serial data at the rising
edge of the shift clock (starting from the lower bits).
