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(ED1) 4 I Data strobe input
Serial data is transferred to the respective latch when LE(ED1) is high. The data is latched when LE(ED1) goes low. Also, a control signal input for an Error Detection Mode and Current Adjust Mode (see Timing Diagram). LE(ED1) has an internal pulldown.
OE(ED2) 13 I Output enable. When OE(ED2) is active (low), the output drivers are enabled; when OE(ED2) is high, all output drivers are turned OFF (blanked). Also, a control signal input for an Error Detection Mode and Current Adjust Mode (see Figure 11). OE(ED2) has an internal pullup.
OUT0 to OUT7 5 to 12 O Constant-current outputs
R-EXT 15 I External Resistor - Connect an external resistor to ground to set the current for all outputs
SDI 2 I Serial-data input to the Shift register
SDO 14 O Serial-data output to the following SDI of next driver IC or to the microcontroller
VDD 16 I Supply voltage
