Product Description

The TLC59281DBQR is a 16-channel Constant Current LED Sink Driver without LED open detection. Each channel can be turned on/off by writing serial data to an internal register. The constant-current value of all 16 channels is set by a single external resistor. The constant-current values are determined by an external resistor (RIREF) placed between IREF and GND. When BLANK is low, the corresponding output is turned on if the data in the on/off control data latch are "1" and remains off if the data are "0". When BLANK is high, all outputs are forced off. The TLC59281 has an on/off control data shift register and data latch. Both the on/off control shift register and latch are 16 bits long and are used to turn the constant-current drivers on and off. The on/off data are latched into the data latch by a rising edge of LAT after the data are written into the on/off control shift register by SIN and SCLK.
