It switches signals up to 300 MHz bandwidth with a 10 Ohm max on-state resistance, making it suitable for audio, video, and low-speed RF routing in portable and industrial equipment. ## 300 MHz bandwidth and 4.2 ns switching — signal-path fit The -3 dB bandwidth of 300 MHz covers composite video, baseband analog signals, and digital signals up to several hundred Mbps. Maximum turn-on time is 4.2 ns and turn-off time is 5 ns, so the switch can handle fast multiplexing without distorting the signal edge. The 10 Ohm on-resistance is specified across the full supply range, so the insertion loss stays consistent regardless of the rail voltage. ## Industrial temperature grade and SC-70-5 footprint The SC-70-5 (SOT-353) package occupies about 2.0 mm × 2.1 mm on the board, fitting dense mixed-signal layouts. Mounting is surface-mount only.","metaTitle":"SN74LVC1G66DCKJ Texas Instruments Analog Switch, 300MHz","metaDescription":"Texas Instruments SN74LVC1G66DCKJ SPST analog switch, 300 MHz bandwidth, 10 Ohm on-resistance, 1.65V-5.5V supply.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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","Product Status":"Obsolete","Switch Circuit":"SPST - NO","lifecycle_stage":"eol_hot","Charge Injection":"-","Number of Circuits":"1","Base Product Number":"SN74LVC1G","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/SN74LVC1G66DCKJ/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for SN74LVC1G66DCKJ?","answer":"Texas Instruments has not published an official successor order code for the SN74LVC1G66DCKJ.
