For SPI at 20 MHz or UART at 3 Mbps, this leaves headroom; for a 50 MHz QSPI interface, the part is not a fit. The open-drain output mode trades speed for multi-drop bus compatibility (I2C, SMBus), while push-pull mode gives the full 24 Mbps. If your design needs 100+ Mbps, look at the SN74LXC2T45DTTR (420 Mbps) or the CAXC4T774QBQBRQ1 (310 Mbps, also AEC-Q100), but note those are 2-channel or unidirectional variants — the TXS0104EQPWRQ1's 4-channel bidirectional topology is rarer in automotive grade. For dual-sourcing, the CAXC4T774QBQBRQ1 (also AEC-Q100, 4-channel bidirectional, 310 Mbps) is a functional alternative, though its supply voltage floor of 0.65 V is lower — verify compatibility with your VCCA/VCCB rails before substituting. ## 14-TSSOP footprint — layout notes Surface-mount only. The auto-direction sensing means no DIR pin to route — just the two supply rails and four bidirectional I/O lines. Decouple each supply pin with a 0.1 µF ceramic placed within 2 mm of the pin; the datasheet recommends 1 µF bulk capacitance per rail if the translator is more than 5 cm from the power source. No thermal pad — junction-to-ambient thermal resistance is handled through the leads and PCB copper.","metaTitle":"TXS0104EQPWRQ1 Automotive Level Shifter, 24 Mbps, AEC-Q100","metaDescription":"TI TXS0104EQPWRQ1 bidirectional voltage-level translator, 4-channel, 24 Mbps, AEC-Q100 qualified, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Auto-Direction Sensing","Data Rate":"24Mbps","Output Type":"Open Drain, Push-Pull","Channel Type":"Bidirectional","Input Signal":"-","Mounting Type":"Surface Mount","Output Signal":"-","Package / Case":"14-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","Voltage - VCCA":"1.65 V ~ 3.6 V","Voltage - VCCB":"2.3 V ~ 5.5 V","Translator Type":"Voltage Level","lifecycle_stage":"eol_hot","Number of Circuits":"1","Base Product Number":"TXS0104","Channels per Circuit":"4","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"14-TSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5100","priceTiers":[{"qty":1,"price":"$1.51000","currency":"USD"},{"qty":10,"price":"$1.35400","currency":"USD"},{"qty":25,"price":"$1.28480","currency":"USD"},{"qty":100,"price":"$1.05550","currency":"USD"},{"qty":250,"price":"$0.98668","currency":"USD"},{"qty":500,"price":"$0.87194","currency":"USD"},{"qty":1000,"price":"$0.68837","currency":"USD"},{"qty":2000,"price":"$0.64941","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/88274c8db2106f40df42e1d678db15dd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TXS0104EQPWRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TXS0104EQPWRQ1 bidirectional?","answer":"Yes.
