Electrical Description
Pin Function Description
RESET (RST)  Sets Control Register bits to logic low. The Dot Register contents are unaected by 
the Reset pin. (logic low = reset; logic high = normal operation).
DATA IN (D
IN
)  Serial Data input for Dot or Control Register data. Data is entered on the rising edge 
of the Clock input.
DATA OUT (D
OUT
)  Serial  Data  output  for Dot  or  Control Register data. This  pin  is  used  for cascading 
multiple displays.
CLOCK (CLK)  Clock input for writing Dot or Control Register data. When Chip Enable is logic low, 
data is entered on the rising Clock edge.
REGISTER SELECT (RS)  Selects Dot Register (RS = logic low) or Control Register (RS = logic high) as the  des-
tination for serial data entry. The logic level of RS is latched on the falling edge of the 
Chip Enable input.
CHIP ENABLE (CE)  This input must be a logic low to write data to the display. When CE returns to logic 
high and CLK is logic low, data is latched to either the LED output drivers or a Control 
Register.
OSCILLATOR SELECT (SEL)  Selects either an internal or external display oscillator source. (logic low = External 
Display Oscillator; logic high = Internal Display Oscillator).
OSCILLATOR (OSC)  Output for the Internal Display Oscillator (SEL = logic high) or input for an External 
Display Oscillator (SEL = logic low).
BLANK (BL)  Blanks the display when logic high. May be modulated for brightness control.
