PIN FUNCTIONS
PIN NUMBER
PIN NAME
FUNCTION
1
V
DD
5 V power pin.
2
DATA
IN (DI)
Serial data input pin.
3
CLOCK (CK)
Clock input pin. The shift register shifts data on the clock's rising edge.
4
LOAD (LD)
Load signal input pin. The data in the D
8
to D
15
are read on the rising edge and the current
load register the is selected from among the Duty Register, the Decode & Digit Register, or
Data Registers 0 to 3. The D
0
to D
7
bits of the 16
bit shift register contain data corresponding
to the same registers just described, which are read on the load signal's falling edge.
5~12
OUT
A to
OUT
Dp
Segment drive output pins. The A to Dp outputs correspond to the seven segments. These
pins output constant sink current. Connect each of these pins to the corresponding LED's
cathode.
13, 21
P
GND
Ground pins, There are two which can be used to ground the output OUT
A to OUT
Dp pins.
14
TEST
IN2
Product test pin. In normal use, be sure to connect to ground.
15
TEST
IN1
Product test pin. In normal use, be sure to connect to ground.
16, 17, 19, 20
DIG
0 to DIG
3
Digit output pins. Each of these pins can control one of the four seven
segment digits in a
display.
These pins output the V
CC
pin voltage as a source current output. Connect these pins to the
LED anodes.
18
V
CC
Power pin for digit output.
22
R
EXT
Current setting pin for the OUT
A to OUT
Dp pins. Connect a resistor between this pin and
ground when setting the current.
23
DATA
OUT (DO) connections.
24
L
GND
Ground pin for logic and analog circuits.
