Constant-Current Sink Capability:  
DESCRIPTION  
The TLC59284 is a 16-channel, constant-current sink  
light-emitting diode (LED) driver. Each channel can  
be individually controlled with  
communications protocol that is compatible with 3.3-V  
or 5-V CMOS logic levels, depending on the  
operating VCC. When the serial data buffer is loaded,  
a LAT rising edge transfers the data to the OUTn  
outputs. The BLANK pin can be used to turn off all  
OUTn outputs during power-on and output data  
latching to prevent unwanted image displays during  
these times. The constant-current value of all 16  
channels is set by a single external resistor.
