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.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
