Texas Instruments TLC5917IPWR TSSOP Display Driver, 7 Segment, 16 Pin Pin, 3 → 5.5 V

The Texas Instruments LED Driver designed to work alone or cascaded. Since each output is independently controlled they can be programmed to be on or off by the user. The high LED voltage allows for the use of a single LED per output or multiple LEDs on a single string. With independently controlled outputs supplied with constant current. The LEDs can be combined in parallel to create higher currents on a single string.

Eight constant current output channels
Output current adjusted through single external resistor
Constant output current invariant to load voltage change
Excellent output current accuracy
Maximum LED Voltage is 20 V
Schmitt trigger Input
