It sits in parallel-backplane or memory-bus interface roles where the direction pin (DIR) and output-enable (OE) control which side drives the bus. The LS family runs from a 5 V supply and draws lower power than the original 74-series TTL while keeping the same logic thresholds. ## Bulk packaging — shelf and handling note (tube or loose), not tape-and-reel. For a rework bench or storeroom that pulls a few pieces at a time, bulk avoids the waste of opening a full reel. Store the tubes in a dry, ESD-safe bin — no moisture-bake requirement before hand-soldering, but keep the leads clean for wave-solder or press-fit sockets.","metaTitle":"74LS245PC Bus Transceiver, LS Series TTL, Active","metaDescription":"74LS245PC bus transceiver from the LS series TTL family.

The 74HCT245 is a high-speed CMOS part that is pin-compatible but uses CMOS input thresholds and typically draws lower quiescent current. If your existing board is designed for LS logic levels, the 74LS245PC is the drop-in replacement; switching to HCT may require checking the input voltage thresholds against the driving device."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/74LS245PC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/74LS245PC when reusing this data.
