Serial data is transferred to the respective latch when LE(ED1) is high. The data is latched when LE(ED1) 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, all output drivers OE(ED2) 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. OUT0–OUT7 Constant-current outputs R-EXT Input used to connect an external resistor for setting up all output currents SDI Serial-data input to the Shift register SDO Serial-data output to the following SDI of next driver IC or to the microcontroller VDD Supply voltage Diagnostic Features OVERTEMPERATURE OPEN-LOAD SHORT TO GND SHORT TO VLED DEVICE(1) DETECTION DETECTION DETECTION DETECTION TLC5916 X X X TLC5917 X X X X (1) The device has one single error register for all these conditions (one error bit per channel).
