The 3-state output lets you float the pin when the output-enable is inactive. The supply range spans 1.65 V to 5.5 V, which means this buffer can operate at any common logic rail from 1.8 V through 5 V. In a mixed-voltage system — say a 3.3 V MCU talking to a 5 V peripheral — the buffer can translate a logic signal in either direction as long as the input thresholds align with the supply. The 74LVC family's 5 V tolerant inputs also accept signals above the supply rail, so the buffer won't latch up when a 5 V signal arrives at a 3.3 V powered device. Any remaining stock in the supply chain is new-old-stock or surplus inventory. If you have this part on a BOM for a sustainment program, you will need to source it through independent distribution on a quoted-to-order basis. ## Package and temperature grade — board-fit details The part comes in a 5-pin SC-70-5 package (also known as SOT-353), which is a small surface-mount footprint suited for dense PCB layouts. The wide temperature grade means the buffer's timing and drive characteristics are guaranteed across the full range, which matters for designs that see thermal cycling.","metaTitle":"SN74LVC1G125DCKJ Buffer, 3-State, 1.65V-5.5V, SC-70-5","metaDescription":"TI SN74LVC1G125DCKJ single non-inverting buffer with 3-state output. 32mA drive, 1.65V-5.5V supply, -40°C to 125°C.

The DCKR is the active TI order code that replaces the obsolete DCKJ."},{"question":"Where can I buy SN74LVC1G125DCKJ?","answer":"Since the SN74LVC1G125DCKJ is obsolete, it is not available through standard factory distribution. It can be sourced through independent distribution channels on a quoted-to-order basis. The functionally identical replacement SN74LVC1G125DCKR is available through normal TI distribution if you can qualify the reel suffix change."},{"question":"Can SN74LVC1G125DCKJ be used as a level shifter?","answer":"Yes, the SN74LVC1G125DCKJ can function as a unidirectional level shifter in many applications. The 74LVC family inputs are 5 V tolerant, so a 5 V signal can drive a 3.3 V powered buffer without damage. However, this is a non-inverting buffer with a 3-state output, not a dedicated level translator — it works for digital signals where the input thresholds are compatible with the output-side supply."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74LVC1G125DCKJ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74LVC1G125DCKJ when reusing this data.
