Constant-Current Sink Capability:

DESCRIPTION

The TLC59284 is a 16-channel, constant-current sink

light-emitting diode (LED) driver. Each channel can

be individually controlled with

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.
