Each switch selects one of four signal paths to a common output, controlled by a digital address line. With a -3 dB bandwidth of 700 MHz, this part passes high-frequency signals cleanly — think video distribution, RF switching, or fast digital multiplexing in test equipment. The -68 dB crosstalk at 5 MHz means adjacent channels stay isolated; you won't see bleed from one input corrupting another at that frequency. ## Switching speed and signal integrity Switch times are 6 ns max for both turn-on and turn-off — fast enough for high-speed data acquisition or automated test systems where channel-to-channel switching must keep pace with the sample clock. The 1.5 pC charge injection is low enough that switching between channels won't glitch a sampled analog signal on a downstream ADC. On-resistance is 17 ohms max — moderate for signal switching, but the 6 pF source-off capacitance and 14 pF drain-off capacitance set the settling time in high-impedance paths. For a 50-ohm system, the RC time constant is under 1 ns; for a 1 k-ohm source, budget around 14 ns to settle to 0.1%. Leakage current is 10 nA max — negligible for most analog front-ends, but if you're multiplexing a 10 M-ohm sensor, that leakage translates to a 0.1 mV offset error at the ADC input. The 0.5 mm lead pitch demands careful PCB layout — route the analog traces with controlled impedance if you're pushing the 700 MHz bandwidth, and keep the supply decoupling capacitors within 2 mm of the V+ pin to maintain the crosstalk spec. The supplier device package is 48-QVSOP, which is the same footprint. Supplied in Bulk packaging — not tape-and-reel. For prototype builds or low-volume production this is fine; for high-volume pick-and-place, you'll need to plan for tube or tray feeding, or request a reeled variant if available. ## Active lifecycle and sourcing Sourced through authorized distribution and independent channels. No stock-holding claim; each order is confirmed per the lot.","metaTitle":"Renesas QS4A215Q1G SP4T Analog Switch, 700 MHz","metaDescription":"Renesas QS4A215Q1G dual SP4T analog switch, 700 MHz bandwidth, -68 dB crosstalk at 5 MHz, 1.5 pC charge injection, 17 ohm R_on, 48-FSOP, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Bulk","Crosstalk":"-68dB @ 5MHz","Mounting Type":"Surface Mount","-3db Bandwidth":"700MHz","Package / Case":"48-FSOP (0.154\\\", 3.90mm Width)","Switch Circuit":"SP4T","lifecycle_stage":"eol_hot","Charge Injection":"1.5pC","Number of Circuits":"2","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-QVSOP","On-State Resistance (Max)":"17Ohm","Switch Time (Ton, Toff) (Max)":"6ns, 6ns","Voltage - Supply, Single (V+)":"5V","Current - Leakage (IS(off)) (Max)":"10nA","Multiplexer/Demultiplexer Circuit":"4:1","Channel Capacitance (CS(off), CD(off))":"6pF, 14pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.77","stockQuantity":28,"priceTiers":[{"qty":45,"price":"$6.77000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a9af9edfd6ec41ebeb2b590127dd6113.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the crosstalk spec for QS4A215Q1G?","answer":"Crosstalk is -68 dB at 5 MHz.
