The switch handles single-supply rails from 4.5 V up to 44 V, or dual supplies from ±4.5 V to ±22 V, which covers 12 V and 24 V automotive buses as well as 48 V industrial rails without external level translation. On-resistance is rated at 2.8 Ω maximum, with channel-to-channel matching of 100 mΩ, keeping insertion loss and gain error low in precision analog paths. The -3 dB bandwidth of 40 MHz and crosstalk of -106 dB at 1 MHz mean the part can multiplex audio, low-frequency sensor outputs, or moderate-speed digital signals without degrading signal integrity.","metaTitle":"TI TMUX7219DGKRQ1 SPDT Analog Switch, 2.8Ω, AEC-Q100","metaDescription":"Texas Instruments TMUX7219DGKRQ1 is a single SPDT analog switch with 2.8Ω max on-resistance, 40 MHz bandwidth, -106 dB crosstalk, and AEC-Q100 qualification.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Grade":"Automotive","Package":"Tape & Reel (TR); Cut Tape (CT)","Crosstalk":"-106dB @ 1MHz","Mounting Type":"Surface Mount","Qualification":"AEC-Q100","-3db Bandwidth":"40MHz","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","Switch Circuit":"SPDT","lifecycle_stage":"eol_hot","Charge Injection":"-16pC","Number of Circuits":"1","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"8-VSSOP","On-State Resistance (Max)":"2.8Ohm","Voltage - Supply, Dual (V±)":"±4.5V ~ 22V","Switch Time (Ton, Toff) (Max)":"168ns, 180ns","Voltage - Supply, Single (V+)":"4.5V ~ 44V","Current - Leakage (IS(off)) (Max)":"100pA (Typ)","Multiplexer/Demultiplexer Circuit":"2:1","Channel-to-Channel Matching (ΔRon)":"100mOhm","Channel Capacitance (CS(off), CD(off))":"34pF, 34pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.9","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.90000","currency":"USD"},{"qty":10,"price":"$4.40400","currency":"USD"},{"qty":25,"price":"$4.16320","currency":"USD"},{"qty":100,"price":"$3.60810","currency":"USD"},{"qty":250,"price":"$3.42308","currency":"USD"},{"qty":500,"price":"$3.07154","currency":"USD"},{"qty":1000,"price":"$2.59045","currency":"USD"},{"qty":2500,"price":"$2.46092","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e6ebaecb9af352a18fee3a9ea2570d5f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the on-resistance of TMUX7219DGKRQ1?","answer":"Maximum on-resistance is 2.8 Ω, with channel-to-channel matching of 100 mΩ."},{"question":"Is TMUX7219DGKRQ1 automotive qualified (AEC-Q100)?","answer":"Yes, the TMUX7219DGKRQ1 is AEC-Q100 qualified and carries an Automotive grade rating."},{"question":"How do I get current pricing and availability for TMUX7219DGKRQ1?","answer":"Submit an RFQ through this listing.
