Description
An external resistor at this terminal establishes maximum output current
Regulator decoupling
Logic ground
Chip power supply voltage; connect to VREG externally if 4.75 V < V IN < 5.5 V
Serial clock input; PWM clock if external clock is selected
Output enable input; when low (active), the output drivers are enabled; when high (inactive), all
output drivers are turned off (blanked)
Latch input terminal; serial data is latched with high-level input
Serial data input to shift register
Sinking output terminal
Power ground
Sinking output terminal
Sinking output terminal
Buffered serial data output after shift register
Buffered latch output
Buffered output enable output
Buffered clock output
Exposed thermal pad, not internally connected; connect externally to LGND and PGND.
