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.
