The 1.27 mm lead pitch gives the pick-and-place a forgiving target; tombstoning risk is low with the 15 mA / 12 mA output drive not pulling enough current to heat the package unevenly during reflow. MSL is not explicitly stated in the record, but the package is a molded SSOP — typical MSL-1 or MSL-2 for this family. If the reel has been opened and the floor life is uncertain, a 24-hour bake at 125°C before reflow is cheap insurance against popcorning. ## Supply rails and temperature — where this fits on the board The 4.75 V to 5.25 V supply range ties it to a 5 V nominal rail — the same bus that powers legacy TTL and 5 V CMOS logic. It will not work on a 3.3 V or lower supply without a level translator at the input. The -40°C to 85°C operating temperature range covers industrial enclosures, outdoor telecom cabinets, and unheated factory floors. ## Output drive — what 15 mA / 12 mA means for fan-out The 15 mA source and 12 mA sink capability at the output is modest by today's 24 mA or 32 mA bus-driver standards. Driving a 50 pF load at 5 V, the output transition time will be around 4–6 ns — fine for a 20–30 MHz clocked bus, but marginal for a 50 MHz+ backplane without a dedicated line driver. The 3-state output allows multiple buffers to share a common data bus — the high-impedance state presents a 10 µA max leakage load to the bus, so 8 to 12 of these can be paralleled without exceeding the bus pull-up current budget. ## Lifecycle and sourcing — active part, quoted to order ROHS3 compliant — the part is lead-free and compatible with standard Pb-free reflow profiles (260°C peak).","metaTitle":"Texas Instruments CY74FCT2541TQCT Buffer, 20-SSOP","metaDescription":"Active Texas Instruments CY74FCT2541TQCT 8-bit non-inverting buffer with 3-state outputs, 20-SSOP package, 4.75-5.25V supply, -40 to 85°C.","metaKeywords":null},"attributes":{"series":"74FCT","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Series":"74FCT","Package":"Tape & Reel (TR); Cut Tape (CT)","Logic Type":"Buffer, Non-Inverting","Output Type":"3-State","Mounting Type":"Surface Mount","Package / Case":"20-SSOP (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.75V ~ 5.25V","Number of Elements":"1","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"20-SSOP","Current - Output High, Low":"15mA, 12mA","Number of Bits per Element":"8"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.94","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.94000","currency":"USD"},{"qty":10,"price":"$0.83800","currency":"USD"},{"qty":25,"price":"$0.79560","currency":"USD"},{"qty":100,"price":"$0.65340","currency":"USD"},{"qty":250,"price":"$0.61076","currency":"USD"},{"qty":500,"price":"$0.53976","currency":"USD"},{"qty":1000,"price":"$0.42612","currency":"USD"},{"qty":2500,"price":"$0.40200","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3e706c869f75b1d7d67518ce3917059a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Will CY74FCT2541TQCT drop into a panel that was specified around SN74LVTH16245ADGVR without rewiring?","answer":"No — the SN74LVTH16245ADGVR is a 48-pin TSSOP transceiver with 2.7 V supply and 32 mA drive, while the CY74FCT2541TQCT is a 20-pin SSOP buffer running on 5 V with 15 mA drive.
