Switch timing of 4.2 ns turn-on and 5 ns turn-off max supports fast multiplexing in data-acquisition front-ends and clock gating applications where the switch must settle before the next sample.","metaTitle":"SN74LVC1G66DCKRG4 TI analog switch, SPST-NO, 10 Ohm, 300 MHz","metaDescription":"Texas Instruments SN74LVC1G66DCKRG4 SPST-NO analog switch, 10 Ohm max on-resistance, 300 MHz bandwidth, SC-70-5, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Crosstalk":"-","Mounting Type":"Surface Mount","-3db Bandwidth":"300MHz","Package / Case":"5-TSSOP, SC-70-5, SOT-353","Switch Circuit":"SPST - NO","lifecycle_stage":"eol_hot","Charge Injection":"-","Number of Circuits":"1","Base Product Number":"74LVC1G66","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SC-70-5","On-State Resistance (Max)":"10Ohm","Voltage - Supply, Dual (V±)":"-","Switch Time (Ton, Toff) (Max)":"4.2ns, 5ns","Voltage - Supply, Single (V+)":"1.65V ~ 5.5V","Current - Leakage (IS(off)) (Max)":"100nA","Multiplexer/Demultiplexer Circuit":"1:1","Channel Capacitance (CS(off), CD(off))":"6pF","Channel-to-Channel Matching (ΔRon)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7a200d61e5d0045e9fe11335fae044c3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN74LVC1G66DCKRG4/alternatives.json"},"ai":{"faq":[{"question":"Can SN74LVC1G66DCKRG4 be used for audio switching?","answer":"Yes.
