Each of the 16 channels delivers up to 40 mA, set by an external resistor, and the output stage handles up to 20 V — enough headroom for multiple series LEDs in a string. The shift register clocks at 30 MHz, which supports PWM dimming or data updates across a multiplexed display without visible flicker. The 24-TSSOP package keeps the footprint compact for dense channel arrays on a sign board or automotive lighting PCB. The wide range means it holds its current accuracy through a cold start in outdoor signage and through the heat soak near an engine bay or LED headlamp assembly. The constant-current topology itself is linear, so thermal dissipation scales with the voltage drop across the output stage — the 24-TSSOP's exposed pad (if present on the layout) needs a thermal via stitch to keep the junction below the derating threshold when driving all 16 channels near the 40 mA ceiling at high ambient. ## Sourcing and lifecycle posture It is a current-production part from STMicroelectronics, not subject to last-time-buy or obsolescence notices at this time. No official replacement or second-source alternate is recorded in the STP16CPPS05TTR's lifecycle documentation; the part is the standard offering in its family.","metaTitle":"ST STP16CPPS05TTR LED Driver, 16-Ch 40mA 24-TSSOP","metaDescription":"STMicroelectronics STP16CPPS05TTR linear LED driver IC, 16 constant-current outputs at 40mA each, 20V output rating, 30MHz shift register, -40 to 125°C.","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":"30MHz","Mounting Type":"Surface Mount","Package / Case":"24-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Voltage - Output":"20V","Number of Outputs":"16","Internal Switch(s)":"Yes","Operating Temperature":"-40°C ~ 125°C (TA)","Voltage - Supply (Max)":"5.5V","Voltage - Supply (Min)":"3V","Supplier Device Package":"24-TSSOP","Current - Output / Channel":"40mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.24","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.24000","currency":"USD"},{"qty":10,"price":"$2.01300","currency":"USD"},{"qty":25,"price":"$1.89920","currency":"USD"},{"qty":100,"price":"$1.61820","currency":"USD"},{"qty":250,"price":"$1.51944","currency":"USD"},{"qty":500,"price":"$1.32952","currency":"USD"},{"qty":1000,"price":"$1.10160","currency":"USD"},{"qty":2500,"price":"$1.02562","currency":"USD"},{"qty":5000,"price":"$0.98764","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/356e9428a222dee64c8e80926c298b27.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output current per channel of STP16CPPS05TTR?","answer":"Each of the 16 outputs sinks a constant 40 mA, set by an external resistor."},{"question":"What is the replacement for STP16CPPS05TTR?","answer":"No official replacement or pin-compatible second source is documented in the STP16CPPS05TTR's lifecycle records.
