The wide single-supply range from 3 V to 20 V or dual supplies from ±2.5 V to 9 V lets it interface with 5 V and 12 V logic and sensor rails without level shifting. On-state resistance is 240 Ohm max, with channel-to-channel matching of 5 Ohm, keeping insertion loss uniform across channels. The 20 MHz -3 dB bandwidth supports analog signals up to video frequencies, and the 100 nA max off-leakage ensures minimal signal bleed in high-impedance sensor inputs. ## Temperature range and package for under-hood use The 16-TSSOP package (4.40 mm width) is surface-mount and fits compact PCB layouts common in ECU and sensor interface modules.","metaTitle":"CD4051BQPWRQ1 Texas Instruments 8:1 Analog Mux, AEC-Q100","metaDescription":"Texas Instruments CD4051BQPWRQ1 8:1 analog multiplexer/demultiplexer, AEC-Q100 automotive grade, single 3V-20V or dual ±2.5V-9V supply, 240 Ohm max","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","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":"-40°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":"$0.2966","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fe244f3f3b0480d6e20246dcefd93df5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does the CD4051BQPWRQ1 have a direct replacement if it becomes obsolete?","answer":"No official replacement or successor part is listed on the manufacturer's record.
