0 V to 5.
5 V • Constant-Current Accuracy: – Channel-to-Channel = ±1% – Device-to-Device = ±1% • CMOS Logic Level I/O • 35-MHz Data Transfer Rate • 20-ns BLANK Pulse Width • Operating Temperature: –40°C to +85°C APPLICATIONS • LED Video Displays • Message Boards • Illumination DESCRIPTION The TLC59281 is a 16-channel, constant-current sink LED driver.
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.
