It routes one analog or digital signal path with a maximum on-resistance of 10 Ohm and a -3 dB bandwidth of 300 MHz, making it suitable for audio, video, and RF switching up to several hundred megahertz. The 10 Ohm max on-resistance sets the insertion loss floor: at 50 Ohm system impedance the switch adds about 0.8 dB loss. The 300 MHz bandwidth means the switch passes signals up to that frequency with minimal roll-off — useful for composite video or baseband RF paths. Switching times of 4.2 ns (ton) and 5 ns (toff) allow the part to handle fast multiplexing in data-acquisition or test-equipment front ends without introducing timing skew.","metaTitle":"SN74LVC1G66DBVRG4 TI SPST Analog Switch, 10 Ohm, 300 MHz","metaDescription":"Texas Instruments SN74LVC1G66DBVRG4 single-pole single-throw analog switch. 10 Ohm max on-resistance, 300 MHz bandwidth, 1.65V to 5.5V supply.","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); Cut Tape (CT)","Crosstalk":"-","Mounting Type":"Surface Mount","-3db Bandwidth":"300MHz","Package / Case":"SC-74A, SOT-753","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":"SOT-23-5","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":"$0.4500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7a200d61e5d0045e9fe11335fae044c3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN74LVC1G66DBVRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the on-resistance of SN74LVC1G66DBVRG4?","answer":"The maximum on-resistance is 10 Ohm.
