For a 1.8 V core logic to 3.3 V peripheral bridge, VCCA gets the 1.8 V rail and VCCB the 3.3 V rail. The 100 Mbps data rate is specified with a 15 pF load — enough margin for a short PCB trace to one or two loads, but you lose speed if the trace runs long or fans out to multiple receivers without buffering. ## Package and footprint — 14-VQFN with exposed pad The TXB0104RGYRG4 comes in a 14-VFQFN exposed-pad package, supplier device package 14-VQFN (3.5x3.5). Surface-mount assembly only. ## Temperature grade — industrial, not extended If your application sees sustained junction temperatures above 85°C — under-hood automotive, downhole, or near a hot power stage — this part is not the right choice; look at the TXB0104-Q1 variant or a translator with a 125°C rating.","metaTitle":"TXB0104RGYRG4 voltage level translator, 100 Mbps, TI","metaDescription":"Texas Instruments TXB0104RGYRG4 4-channel bidirectional level translator. 100 Mbps data rate, 1.2 V to 5.5 V dual supply, auto-direction sensing.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Auto-Direction Sensing","Data Rate":"100Mbps","Output Type":"Tri-State, Non-Inverted","Channel Type":"Bidirectional","Input Signal":"-","Mounting Type":"Surface Mount","Output Signal":"-","Package / Case":"14-VFQFN Exposed Pad","Voltage - VCCA":"1.2 V ~ 3.6 V","Voltage - VCCB":"1.65 V ~ 5.5 V","Translator Type":"Voltage Level","lifecycle_stage":"eol_hot","Number of Circuits":"1","Base Product Number":"TXB0104","Channels per Circuit":"4","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"14-VQFN (3.5x3.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c98cf2dc6bf614899e44e306393cd5f7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TXB0104RGYRG4/alternatives.json"},"ai":{"faq":[{"question":"Is TXB0104RGYRG4 bidirectional?","answer":"Yes, all four channels are bidirectional with auto-direction sensing — no direction-control pin is needed.
