The 14-SOIC package with surface-mount footprint is a standard layout that fits most two-layer boards without requiring fine-pitch assembly. The single-circuit design with four channels per circuit packs four independent translation paths into one SOIC-14 package, keeping the board area tight. For reel quantities, the TXB0104DGV4 variant is the tape-and-reel counterpart.","metaTitle":"TXB0104DG4 Voltage Level Translator, 100 Mbps, 14-SOIC","metaDescription":"Texas Instruments TXB0104DG4 4-channel bidirectional voltage-level translator with 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":"Tube","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-SOIC (0.154\\\", 3.90mm Width)","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-SOIC"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.9500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c98cf2dc6bf614899e44e306393cd5f7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TXB0104DG4/alternatives.json"},"ai":{"faq":[{"question":"Does TXB0104DG4 support I2C?","answer":"The TXB0104DG4 is a general-purpose bidirectional level translator rated for data rates up to 100 Mbps. I2C typically runs at 100 kHz or 400 kHz, well within this part's speed capability. However, I2C uses open-drain signaling with pull-up resistors, and the TXB0104's auto-direction sensing works with open-drain buses. For pure I2C applications, TI also offers dedicated I2C translators like the TCA9406 or PCA9306, which include integrated pull-up current sources and better handle the I2C bus capacitance."},{"question":"What is the difference between TXB0104 and TXB0108?","answer":"The TXB0104 provides four bidirectional channels in a 14-SOIC package, while the TXB0108 offers eight channels in a 20-SOIC or 20-TSSOP package. Both share the same 100 Mbps data rate, auto-direction sensing, and dual-supply range. The choice is purely channel count versus board area — the TXB0104 fits when four lines are enough, saving space and cost over the eight-channel variant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TXB0104DG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TXB0104DG4 when reusing this data.
