Terminal Descriptions
DESCRIPTION
Clock input for data shift on rising edge
Ground for control logic and current sink
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.
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.
Constant-current outputs
Input used to connect an external resistor (R_ext) for setting output currents
Serial-data input to the Shift register
Serial-data output to the following SDI of next driver IC or to the microcontroller
Supply voltage
