It operates across a supply range of 1.65 V to 5.5 V, making it suitable for mixed-voltage systems where a 3.3 V core interfaces with a 1.8 V or 5 V peripheral. The output enable (OE) pin, active low, places the output in a high-impedance state, allowing multiple devices to share a common bus without contention. The 74LVC1G125DBVTG4 sources and sinks 32 mA at both high and low output states. This symmetric drive capability is sufficient to drive a single TTL load or a short unterminated trace on a backplane. For longer traces or higher fan-out, the 32 mA limit sets the maximum capacitive load at a given switching frequency — a 50 pF load at 50 MHz will draw roughly 8 mA dynamic current, leaving headroom for DC loads. The 3-state output allows the buffer to be disconnected from the bus when not selected, which is essential in shared data lines or multiplexed address buses. ## SOT-23-5 package — footprint and layout notes The five-pin footprint occupies approximately 3 mm × 3 mm on the board, with a 0.95 mm pin pitch. The SOT-23-5 is a standard surface-mount package compatible with reflow soldering and is widely second-sourced across the industry.","metaTitle":"74LVC1G125DBVTG4 Buffer, Non-Inverting, 3-State, SOT-23-5","metaDescription":"Texas Instruments 74LVC1G125DBVTG4 single buffer with 3-state output, 1.65V–5.5V supply, 32mA drive, -40°C to 125°C.

The 74LVC1G125DBVTG4 is specifically the SOT-23-5 variant. Both are pin-compatible and electrically identical for the same package option, so they can be used interchangeably in a design that accepts the SOT-23-5 footprint."},{"question":"What is the difference between 74LVC1G125 and 74LVC1G126?","answer":"Both are single-bit non-inverting buffers with 3-state outputs. The difference is the output enable polarity: the 74LVC1G125 uses an active-low OE pin (output enabled when OE is low), while the 74LVC1G126 uses an active-high OE pin (output enabled when OE is high). The 74LVC1G125 is the more common choice for bus isolation where a low-true enable signal is available."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/74LVC1G125DBVTG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/74LVC1G125DBVTG4 when reusing this data.
