The 16-TSSOP package (4.40 mm width) is a compact surface-mount footprint for dense PCB layouts. ## Supply flexibility and channel matching Single-supply operation spans 3 V to 20 V, or dual supplies from ±2.5 V to ±9 V, allowing the part to work in both single-rail and split-rail systems. The 5 Ohm channel-to-channel matching keeps the Ron variation tight across channels, which matters when the mux is used in a gain-scaling or precision divider network where each channel must present the same source impedance. Max off-leakage current is 100 nA, low enough for most sensor and data-acquisition front ends without introducing noticeable offset error. Channel capacitance is 0.2 pF on the source side and 30 pF on the drain side — the drain capacitance dominates the settling time when switching between channels.","metaTitle":"CD4051BPW 8:1 Analog Multiplexer/Demultiplexer, 240 Ohm","metaDescription":"TI CD4051BPW 8:1 analog mux/demux in 16-TSSOP. 240 Ohm max on-resistance, -55°C to 125°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tube","Crosstalk":"-","Mounting Type":"Surface Mount","-3db Bandwidth":"20MHz","Package / Case":"16-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","Switch Circuit":"-","lifecycle_stage":"eol_hot","Charge Injection":"-","Number of Circuits":"1","Base Product Number":"CD4051","Operating Temperature":"-55°C~125°C(TA)","Supplier Device Package":"16-TSSOP","On-State Resistance (Max)":"240Ohm","Voltage - Supply, Dual (V±)":"±2.5V ~ 9V","Switch Time (Ton, Toff) (Max)":"-","Voltage - Supply, Single (V+)":"3V ~ 20V","Current - Leakage (IS(off)) (Max)":"100nA","Multiplexer/Demultiplexer Circuit":"8:1","Channel Capacitance (CS(off), CD(off))":"0.2pF, 30pF","Channel-to-Channel Matching (ΔRon)":"5Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2f82f8b629955ed19c1134c46ca4405e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can I order CD4051BPW in a tube or reel?","answer":"The CD4051BPW is listed with a Tube package option.
