It handles open-drain and push-pull outputs at up to 24 Mbps, making it a common choice for I2C, SPI, and UART level shifting between 1.8V, 2.5V, 3.3V, and 5V logic families. The 1.65 V minimum on VCCA also covers 1.8 V logic with margin, answering the common question of whether this part works with 1.8 V logic (it does, on the A-side). ## Data rate and I2C compatibility Rated at 24 Mbps, this translator comfortably exceeds the 400 kHz (Fast-mode) and 1 MHz (Fast-mode Plus) I2C data rates. It is suitable for I2C level shifting as long as the bus capacitance and pull-up resistors stay within the device's drive capability — the open-drain output type supports the wired-AND signalling I2C requires. For higher-speed serial interfaces like SPI at 10+ MHz, the 24 Mbps ceiling is adequate for most 8- and 16-bit transfers, but check the bus timing margin at your target frequency. ## Package and footprint notes for the shop floor The part is surface-mount only. No MSL rating is listed in the spec record, so assume MSL 1 (no bake required) unless the reel label says otherwise; if the pouch seal is broken, bake at 125°C for 48 hours before reflow to be safe. It is a standard production part from Texas Instruments, available through independent distribution.","metaTitle":"TXS0104ERGYR Voltage Level Translator, 24 Mbps","metaDescription":"TI TXS0104ERGYR 4-channel bidirectional voltage-level translator. 24 Mbps data rate, auto-direction sensing, 1.65-3.6V VCCA / 2.3-5.5V VCCB.

Both use the same auto-direction sensing architecture and support similar supply voltage ranges and data rates. The 4-channel version is the choice when you need to translate multiple signals (e.g., an I2C bus plus a reset line) in a single IC."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TXS0104ERGYR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TXS0104ERGYR when reusing this data.
