The SN74ALS08DR is pin-compatible with the older SN74LS08 and runs on the same 5 V supply. The ALS version is faster (14 ns vs about 18 ns for LS) and draws slightly more supply current. If the original board was designed with LS08 timing margins, the ALS08 will work as a drop-in replacement and may even improve setup timing. The only catch is the higher input current of ALS versus LS — check that the driving gate can source the additional 20 µA per input; in practice it rarely matters."},{"question":"What are the alternatives to SN74ALS08DR?","answer":"The closest functional alternative in the same 74ALS family is the SN74ALS11ANS, which is a triple 3-input AND gate in a different package (14-SOIC but tube instead of tape-and-reel). It has three gates instead of four, and each gate has three inputs instead of two. For a direct quad 2-input replacement, the SN74F00DR is a NAND gate (not AND) from the faster 74F family with 5 ns propagation delay, but the logic function is inverted. If you need the exact AND function, stick with the SN74ALS08DR or cross to the 74ACT08 which offers similar speed with CMOS-level inputs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74ALS08DR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74ALS08DR when reusing this data.
