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 pulldown 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 output
OUT1 6 O Constant-current output
OUT2 7 O Constant-current output
OUT3 8 O Constant-current output
OUT4 9 O Constant-current output
OUT5 10 O Constant-current output
OUT6 11 O Constant-current output
OUT7 12 O Constant-current output
OUT8 13 O Constant-current output
OUT9 14 O Constant-current output
OUT10 15 O Constant-current output
OUT11 16 O Constant-current output
OUT12 17 O Constant-current output
OUT13 18 O Constant-current output
OUT14 19 O Constant-current output
OUT15 20 O Constant-current output
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 — Supply voltage
