16-channel constant-current sink with shift-register interface
The TLC59282DBQR is a 16-channel constant-current sink LED driver from Texas Instruments, built around a 35 MHz shift register topology. Internal switches are integrated, so no external driver FETs are needed per channel — the 24-SSOP package keeps the BOM count low for a 16-output design.
Supply rails and temperature range
The 35 MHz shift-rate means a 16-channel frame updates in under 500 ns at full speed, leaving plenty of margin for PWM dimming at kHz rates without visible flicker.
Package and board-fit
The SSOP footprint is common enough that most assembly houses run it without a setup charge. Cut Tape works for prototypes or small-batch repairs where only a handful of parts are needed.
ROHS3 compliant, so it ships into EU and UKCA markets without exemption paperwork.
