Output high 400 µA, output low 8 mA. Input thresholds 0.5V low, 1.9V high. ## Package and handling notes The 14-SSOP package (0.209 inch body width, 5.30 mm) is a standard fine-pitch SOIC variant. Reel and cut-tape options are both available — cut tape is handy for prototype or small-run builds. No special ESD precautions beyond normal handling; the 74LS family is generally robust.","metaTitle":"SN74LS14DBR Schmitt-Trigger Inverter, 74LS Series, 14-SSOP","metaDescription":"SN74LS14DBR is a 6-channel Schmitt-trigger inverter from the 74LS series.

The logic function, thresholds, and timing are the same. For a drop-in replacement on an existing board, verify the footprint matches."},{"question":"What is a good second-source or alternative for SN74LS14DBR?","answer":"For a drop-in functional replacement, the SN74HCS04PWR (74HCS series) is a modern alternative: six Schmitt-trigger inverters, but operates from 2V to 6V, has faster propagation delay (16 ns at 6V/50 pF), and a wider temperature range (-40°C to 125°C). It is not pin-for-pin compatible due to different supply voltage range, but serves the same logic role in 3.3V or 5V systems. The SN74LVU04APWT (74LVU series) is another 5V option with 7 ns delay, but lacks Schmitt-trigger inputs."},{"question":"Is SN74LS14DBR Schottky?","answer":"Yes — the 'LS' in 74LS stands for Low-Power Schottky, meaning it uses Schottky-clamped transistors for faster switching with lower power than standard TTL. The Schmitt-trigger inputs are a separate feature for noise immunity."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74LS14DBR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74LS14DBR when reusing this data.
