Product Overview
The TLC5916 is a Texas Instruments 8-channel constant-current LED sink driver for LED control designs that need matched sink outputs. Each of the eight outputs is independently controlled, with recommended output current from 3 mA to 120 mA per channel. Output current is set by one external resistor connected from R-EXT to ground, and a 256-step programmable global current gain provides system-level current adjustment.

Procurement Notes
When requesting a quote for TLC5916, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For LED and optoelectronic sourcing, brightness bin, wavelength or color temperature bin, forward voltage range, viewing angle, moisture sensitivity level and soldering process limits may affect final selection, availability and lead time.
