DESCRIPTION
The TLC59283 is a 16-channel, constant-current sink
light-emitting diode (LED) driver. Each channel can
be individually controlled with a simple serial
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.
Each constant-current output has a pre-charge field-
effect transistor (FET) that can reduce ghosting on
the multiplexing (dynamic) drive LED display. Multiple
TLC59283s 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.
