TLC59282DBQR

产品概述

The TLC59282DBQR is a 16-channel constant-current LED Driver with 4-channel grouped delay for noise reduction. Each channel can be individually controlled via a simple serial communications protocol that is compatible with 3.3 or 5V 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 LEDs 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.
