Each of the 16 channels delivers up to 35 mA, set by an external resistor, with the output stage rated to 17 V for driving series LED strings. The shift register clocks at 35 MHz, enabling fast data updates for multiplexed or PWM-dimming applications. Supply range is 3 V to 5.5 V, and the device operates over -40 °C to 85 °C ambient, suiting it for indoor signage, industrial panel indicators, and general-purpose constant-current LED control. ## Shift register topology and 35 MHz clock — what it means for your update rate The TLC5928PWR uses a shift-register interface (data in, clock, latch, output enable) rather than a serial bus like I²C or SPI. The 35 MHz clock rate means you can shift in 16 bits of data in under 500 ns, then latch and update all outputs simultaneously. This is fast enough for 8-bit PWM dimming at several kHz per channel without visible flicker, provided the host MCU can feed the data stream. The open-drain outputs sink current, so the LED common anode connects to a supply up to 17 V. ## Active lifecycle — no last-time-buy pressure The TLC5928PWR carries an Active product status, meaning Texas Instruments continues to manufacture and support the part. There is no announced end-of-life or last-time-buy window. For production planning, this removes the urgency to stockpile or qualify a replacement. The part is ROHS3 compliant and ships in Tape & Reel or Cut Tape options for the 24-TSSOP package.","metaTitle":"TLC5928PWR LED Driver IC, 16-Channel 35mA 24-TSSOP","metaDescription":"Texas Instruments TLC5928PWR linear LED driver with 16 constant-current outputs, 35 mA per channel, 17 V output rating, 35 MHz shift register, 3 V to 5.5 V","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Linear","Package":"Tape & Reel (TR); Cut Tape (CT)","Topology":"Shift Register","Frequency":"35MHz","Mounting Type":"Surface Mount","Package / Case":"24-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Voltage - Output":"17V","Number of Outputs":"16","Internal Switch(s)":"Yes","Operating Temperature":"-40°C ~ 85°C (TA)","Voltage - Supply (Max)":"5.5V","Voltage - Supply (Min)":"3V","Supplier Device Package":"24-TSSOP","Current - Output / Channel":"35mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.66","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.66000","currency":"USD"},{"qty":10,"price":"$1.48500","currency":"USD"},{"qty":25,"price":"$1.40960","currency":"USD"},{"qty":100,"price":"$1.15800","currency":"USD"},{"qty":250,"price":"$1.08252","currency":"USD"},{"qty":500,"price":"$0.95664","currency":"USD"},{"qty":1000,"price":"$0.75525","currency":"USD"},{"qty":2000,"price":"$0.71250","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/76d0afd05a539610df3b6ffba099df70.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum output current per channel for TLC5928PWR?","answer":"Each of the 16 constant-current sink outputs is rated for 35 mA maximum.
