DESCRIPTION
I
Clock input pin for data shift on rising edge
— Ground pin for control logic and current sink
Data strobe input pn
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.
LE(ED1) has an internal pulldown.
Output enable pin. When OE (ED2)(active) is low, the output drivers are enabled; when OE(ED2) is
I
high, all output drivers are turned OFF (blanked). Also, a control signal input for an Error Detection
mode and Current Adjust mode). OE(ED2) has an internal pullup.
O Constant-current output pins
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 pin
-
Thermal pad (exposed center pad) to alleviate thermal stress. Tie to GND. See Layout Guidelines for
more information. (PWP package only)
