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(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) 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 1). OE(ED2) has an internal pullup.
Constant-current outputs
Input used to connect an external resistor for setting up all output currents
Serial-data input to the Shift register
Serial-data output to the following SDI of next driver IC or to the microcontroller
