It operates from a 4.5V to 5.5V supply and is packaged in a 14-SOIC surface-mount package. The commercial temperature range (0°C to 70°C) suits it for office equipment, appliance controllers, and indoor PCB-level signal distribution where 5V logic is the standard. ## Output drive and bus loading Each buffer can source 15 mA and sink 64 mA, giving it the headroom to drive a heavily loaded 5V bus or multiple CMOS inputs without external line drivers. The 3-state outputs let multiple buffers share a common data line — the output enable per channel is independent, so you can gate each signal individually. ## Lifecycle and sourcing The SN74F125D carries an active lifecycle status and is ROHS3 compliant. No last-time-buy or successor has been announced, so it remains a safe choice for new designs requiring a 5V bipolar buffer.","metaTitle":"SN74F125D 74F Buffer, Non-Inverting, 3-State, 14-SOIC","metaDescription":"SN74F125D 74F series quad buffer with 3-state outputs, 4.5V–5.5V supply, 15mA/64mA drive, 0°C–70°C.

The supply voltage range is the same (5V nominal)."},{"question":"Can the SN74F125D be used as a level shifter?","answer":"The SN74F125D is a 5V-only device. It can buffer 5V logic signals but cannot translate between 3.3V and 5V domains without external pull-up or level-shift circuitry. For mixed-voltage translation, a dedicated level shifter or a 74LVC series part would be more appropriate."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74F125D","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74F125D when reusing this data.
