The push-pull output delivers 32mA source and sink, enough to drive a modest LED, a logic input fan-out of several loads, or a short PCB trace. The wide supply range is the headline feature. A 1.8V microcontroller talking to a 3.3V peripheral? This buffer sits between them, powered from the 3.3V rail, and the input thresholds track the supply so a 1.8V logic-high is recognised as a valid high. The same part works in a 5V legacy bus without a separate level shifter. One line item on the BOM covers multiple voltage interfaces, which simplifies procurement and qualification. ## 32mA output drive — enough for real loads The 32mA push-pull output is not just for logic fan-out. It can directly drive a small indicator LED with a series resistor, or buffer a clock signal across a short backplane trace. The symmetrical source and sink current means the output waveform stays balanced, reducing duty-cycle distortion on a 1 MHz clock line. For heavier loads, the same family offers 50mA variants, but for most board-level buffering 32mA is the sweet spot. No last-time-buy notice, no end-of-life schedule. This part is qualified for ongoing production and new designs. The 5-DSBGA package is a standard TI offering, so supply continuity is solid. For dual-sourcing, the same die is available in SOT-23 and SC-70 packages (SN74LVC1G34DBVR, SN74LVC1G34DCKR) if the board can accommodate a larger footprint.","metaTitle":"SN74LVC1G34YZTR Buffer, Non-Inverting, 1.65V-5.5V, 32mA","metaDescription":"Texas Instruments SN74LVC1G34YZTR single-gate buffer, non-inverting, push-pull output. 1.65V to 5.5V supply, 32mA drive, -40°C to 85°C.

The SN74LVC1G34 is a simple non-inverting buffer with no enable — the output always follows the input. If you need bus isolation or shared-line control, choose the SN74LVC1G125. For a fixed buffer path, the SN74LVC1G34 is the simpler, lower-cost choice."},{"question":"Can SN74LVC1G34 be used as a level shifter?","answer":"Yes. The SN74LVC1G34 can translate between voltage domains because its input thresholds scale with VCC. For example, power the device at 3.3V, and a 1.8V logic-high is recognised as a valid high. The output swings rail-to-rail at 3.3V. This works for unidirectional level shifting up to the supply voltage. For bidirectional translation, a dedicated level shifter like the TXB0104 is needed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74LVC1G34YZTR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74LVC1G34YZTR when reusing this data.
