The 2:1 multiplexer/demultiplexer circuit means it can select between two signal sources or route a single signal to one of two destinations. The 300 MHz -3 dB bandwidth tells you it passes high-speed digital clocks, video signals, or RF envelopes up to the VHF band without rolling off—useful for switching between two antenna feeds or multiplexing a high-speed data line. On-resistance is 15 Ohm max. That resistance, combined with the 5.2 pF off-channel capacitance, sets the insertion loss and isolation at high frequencies. ## Supply voltage range and temperature grade That makes the part a natural fit for mixed-voltage boards where the switch needs to pass signals between different logic families. ## Switching speed and charge injection Turn-on time is 5.7 ns max, turn-off is 3.8 ns max, so the switch can handle fast multiplexing or signal gating without introducing timing skew. Charge injection is 7 pC typical, which is low enough that glitch energy on the signal path stays small—important when switching a sample-and-hold input or a precision ADC reference. Channel-to-channel on-resistance matching is 100 mOhm, so the two switch legs behave nearly identically. That matters when the switch is used in a differential signal path or a gain-setting network where the resistance balance affects accuracy.","metaTitle":"74LVC1G3157DBVRG4 SPDT Analog Switch, 15 Ohm, 300 MHz","metaDescription":"Texas Instruments 74LVC1G3157DBVRG4 single SPDT analog switch, 15 Ohm on-resistance, 300 MHz bandwidth, 1.65 V to 5.5 V supply, SOT-23-6.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"74LVC","Package":"Tape & Reel (TR)","Crosstalk":"-54dB @ 10MHz","Mounting Type":"Surface Mount","-3db Bandwidth":"300MHz","Package / Case":"SOT-23-6","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":"SOT-23-6","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-to-Channel Matching (ΔRon)":"100mOhm","Channel Capacitance (CS(off), CD(off))":"5.2pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b6fd206e465edfdf7e43277a272030eb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/74LVC1G3157DBVRG4/alternatives.json"},"ai":{"faq":[{"question":"Is 74LVC1G3157DBVRG4 RoHS compliant?","answer":"The part is lead-free and RoHS compliant as indicated by the G4 suffix in the order code.
