The 4.75V to 5.25V supply rail matches standard 5V digital buses; the 7 mA supply current covers the internal logic and output sink drivers, not the LED segment current itself.","metaTitle":"SN74LS247DR BCD-to-7-Segment LED Driver, 16-SOIC, 4.75-5.25V","metaDescription":"Texas Instruments SN74LS247DR BCD-to-7-segment LED driver in 16-SOIC.

Both accept BCD input and drive 7-segment LED displays, but the package difference means a board layout change is required. The supply voltage ranges also differ: the 74LS family runs on 4.75-5.25V, while the 74HCT version operates down to 4.5V."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74LS247DR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74LS247DR when reusing this data.
