Its 15 Ohm max on-state resistance keeps insertion loss low in RF and baseband signal chains, while the 340 MHz -3dB bandwidth means it passes high-speed digital or analog signals without rolling off the edge rate. ## Bandwidth and crosstalk — the analog path budget With 340 MHz of -3dB bandwidth and -54 dB crosstalk at 10 MHz, this switch handles RF multiplexing, high-speed ADC input selection, and audio routing without injecting channel bleed. The 7 pC charge injection is low enough that sampling glitches stay below the noise floor of a 12-bit ADC at moderate throughput. Channel-to-channel on-resistance matching is held to 100 mOhm, so gain errors in differential or multiplexed paths are minimal. ## Package and footprint — 6-UFDFN land pattern The 6-UFDFN package (1.45 x 1.0 mm body, 0.50 mm pitch) is a tiny SON footprint suited for space-constrained designs like handheld radios, sensor modules, or portable instrumentation. The supplier device package is 6-SON (1.45x1). Surface-mount assembly requires a standard lead-free reflow profile; no thermal pad or exposed paddle to manage. ## Supply and temperature — industrial-grade flexibility Maximum leakage current (IS(off)) is 1 µA, so the switch doesn't drain the rail in battery-powered designs.","metaTitle":"SN74LVC1G3157DRY2 SPDT Analog Switch, 15 Ohm R_on, 340 MHz","metaDescription":"Texas Instruments SN74LVC1G3157DRY2 single SPDT analog switch, 15 Ohm max on-resistance, 340 MHz bandwidth, 1.65 V to 5.5 V 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":"-54dB @ 10MHz","Mounting Type":"Surface Mount","-3db Bandwidth":"340MHz","Package / Case":"6-UFDFN","Product Status":"Active","Switch Circuit":"SPDT","lifecycle_stage":"eol_hot","Charge Injection":"7pC","Number of Circuits":"1","Base Product Number":"74LVC1G3157","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"6-SON (1.45x1)","On-State Resistance (Max)":"15Ohm","Voltage - Supply, Dual (V±)":"-","Switch Time (Ton, Toff) (Max)":"5.7ns, 3.8ns","Voltage - Supply, Single (V+)":"1.65V ~ 5.5V","Current - Leakage (IS(off)) (Max)":"1µA","Multiplexer/Demultiplexer Circuit":"2:1","Channel Capacitance (CS(off), CD(off))":"5.2pF","Channel-to-Channel Matching (ΔRon)":"100mOhm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1134","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b6fd206e465edfdf7e43277a272030eb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN74LVC1G3157DRY2/alternatives.json"},"ai":{"faq":[{"question":"What is the on-state resistance of SN74LVC1G3157DRY2?","answer":"The maximum on-state resistance is 15 Ohm across the full supply range and temperature."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74LVC1G3157DRY2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74LVC1G3157DRY2 when reusing this data.
