DESCRIPTION  
The TLC59282 is a 16-channel, constant-current sink  
driver. Each channel can be individually controlled via  
a simple serial communications protocol that is  
compatible with 3.3 V or 5 V CMOS logic levels,  
depending on the operating VCC. Once the serial  
data buffer is loaded, a rising edge on LATCH  
transfers the data to the LEDx 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. Multiple TLC59282s can be  
cascaded together to control additional LEDs from the  
same processor.  
Constant-Current Accuracy:  
–
Channel-to-Channel = ±0.6% (typ),  
±2% (max)  
–
Device-to-Device = ±1% (typ), ±3% (max)
