DESCRIPTION
I Clock input for data shift on rising edge
— Ground for control logic and current sink
Data strobe input
I
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.
Output enable. When OE (ED2)(active) is low, the output drivers are enabled; when OE(ED2) is high, all
I output drivers are turned OFF (blanked). Also, a control signal input for an Error Detection mode and
Current Adjust mode (See Device Functional Modes). OE(ED2) has an internal pullup.
O Constant-current output
I Input pin 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
I Supply voltage
— Connect to GND. The thermal pad should be soldered to ground in all applications.
(1) The exposed Thermal PAD should be connected to ground in all applications.
