Pin Functions

PIN I/O DESCRIPTION
NAME NO.
CLK 3 I Clock input for data shift on rising edge
GND 1 — Ground for control logic and current sink
LE 4 I Data strobe input
Serial data is transferred to the respective latch when LE is high.
The data is latched when LE goes low.
LE has an internal pull-down resistor.
OE 21 I Output enable
When OE is active (low), the output drivers are enabled.
When OE is high, all output drivers are turned OFF (blanked).
OE has an internal pullup resistor.
OUT0 5 O Constant-current outputs
OUT1 6
OUT2 7
OUT3 8
OUT4 9
OUT5 10
OUT6 11
OUT7 12
OUT8 13
OUT9 14
OUT10 15
OUT11 16
OUT12 17
OUT13 18
OUT14 19
OUT15 20
R-EXT 23 I Input used to connect an external resistor (Rext) for setting output currents
SDI 2 I Serial-data input to the Shift register
SDO 22 O Serial-data output to the following SDI of next driver IC or to the microcontroller
VDD 24 I Supply voltage
