It accepts a supply voltage between 4.5 V and 5.5 V and drives outputs up to 17 V. The shift-register topology means you load grayscale or on/off data serially, then latch it to all outputs simultaneously — useful for LED panels, signage, or indicator arrays where you need independent control per channel without a separate PWM controller per LED.","metaTitle":"TLC5921DAPR LED Driver IC, 16-Ch 80mA Linear, 32-HTSSOP","metaDescription":"Texas Instruments TLC5921DAPR linear LED driver with 16 constant-current outputs at 80 mA each. 20 MHz shift register, 4.5-5.5V supply, 32-HTSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Type":"Linear","Package":"Tape & Reel (TR); Cut Tape (CT)","Topology":"Shift Register","Frequency":"20MHz","Mounting Type":"Surface Mount","Package / Case":"32-TSSOP (0.240\\\", 6.10mm Width) Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Output":"17V","Number of Outputs":"16","Internal Switch(s)":"Yes","Operating Temperature":"-20°C ~ 85°C (TA)","Voltage - Supply (Max)":"5.5V","Voltage - Supply (Min)":"4.5V","Supplier Device Package":"32-HTSSOP","Current - Output / Channel":"80mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.03","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.03000","currency":"USD"},{"qty":10,"price":"$2.72500","currency":"USD"},{"qty":25,"price":"$2.57040","currency":"USD"},{"qty":100,"price":"$2.19010","currency":"USD"},{"qty":250,"price":"$2.05640","currency":"USD"},{"qty":500,"price":"$1.79936","currency":"USD"},{"qty":1000,"price":"$1.49089","currency":"USD"},{"qty":2000,"price":"$1.45500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/1c22fb80d510859a1487acc8e678c255.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the alternatives to TLC5921DAPR?","answer":"The LM2703MF-ADJ/NOPB is a different class of part — a DC-DC boost regulator for backlight applications with a single 0.35 A output.
