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.
