No level translator is needed when mixing these domains in the same design, as long as the output current stays within the 8mA per pin rating. The 3-state output allows the buffer to be placed on a shared bus without contention when the output enable is driven low. The product status is Active.

The supply voltage range of 2V to 5.5V includes 3.3V. At 3.3V the buffer's input thresholds and output drive levels are compatible with standard 3.3V CMOS logic. The 8mA output drive at both high and low levels is sufficient for driving a single CMOS input or a lightly loaded trace."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/74AHC1G126MDCKTEP","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/74AHC1G126MDCKTEP when reusing this data.
