DESCRIPTION
I
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(ED1) is high. The data is
I
latched when LE(ED1) goes low. Also, LE(ED1) is a control signal input for an Error Detection mode
and Current Adjust mode (See Timing Diagram). LE(ED1) has an internal pulldown.
Output enable. When OE(ED2) is active (low), the output drivers are enabled; when OE(ED2) is high,
I
all output drivers are turned OFF (blanked). Also, OE(ED2) is a control signal input for an Error
Detection mode and Current Adjust mode (See Timing Diagram). OE(ED2) has an internal pullup.
O Constant-current outputs
I
Input used to connect an external resistor for setting up all output currents
I
Serial-data input to the Shift register
O Serial-data output to the following SDI of next driver IC or to the microcontroller
