It provides bidirectional voltage-level translation between two independent supply rails, each operating from 1.65V up to 5.5V. The part integrates two 8-bit elements with 3-state outputs, each capable of sinking or sourcing 32mA. Typical applications include mixed-voltage system interfaces, memory-bus translation, and general-purpose level shifting in telecom, industrial control, and computing equipment where 3.3V and 1.8V or 5V domains must communicate. ## Supply range and level translation — the key decision driver It allows direct translation between any two standard logic voltages within that window — for example, 1.8V to 3.3V, 2.5V to 5V, or 3.3V to 1.8V. The direction control pins (DIR) per element set the data flow, and the output-enable (OE) pin puts all outputs into high-impedance state for bus isolation. ## Package and footprint — 24-SSOP narrow-body The narrow-body width saves lateral board space compared to a 24-SOIC wide-body (7.5mm) or 24-TSSOP (4.4mm) alternative. It is ROHS3 compliant. For production BOM lines, this part presents no imminent obsolescence risk.","metaTitle":"SN74LVC8T245DBQR Translation Transceiver, 24-SSOP","metaDescription":"TI SN74LVC8T245DBQR dual-supply 8-bit translation transceiver in 24-SSOP.

The SN74LVC8T245 is a dual-supply translation transceiver with separate VCCA and VCCB rails for level shifting between different voltage domains. The SN74LVC245 is a single-supply octal bus transceiver without voltage translation capability. The 8T245 handles bidirectional level translation; the 245 does not."},{"question":"Does SN74LVC8T245DBQR require external components for level translation?","answer":"No external pull-up resistors or additional level-shifter ICs are required for typical bidirectional or unidirectional data translation. The part integrates the direction control and output-enable logic. Only decoupling capacitors on each supply rail (VCCA and VCCB) are recommended per standard high-speed logic layout practice."},{"question":"What is the lifecycle status of SN74LVC8T245DBQR?","answer":"The part is ROHS3 compliant. There is no reported end-of-life or last-time-buy schedule."},{"question":"Can SN74LVC8T245 be used for I2C level shifting?","answer":"The SN74LVC8T245 is a standard CMOS translation transceiver with 3-state outputs. I2C requires open-drain outputs with pull-up resistors for bus arbitration. This part's push-pull outputs will conflict with the I2C bus architecture. For I2C level shifting, use a dedicated open-drain translator such as the TXS0108E or PCA9306."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74LVC8T245DBQR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74LVC8T245DBQR when reusing this data.
