For a part this mature, the independent channel is the normal route — franchised distributors may carry limited depth, but the part is readily available through the surplus and excess market.","metaTitle":"74LS28PC NOR Gate, Active, Bulk Package","metaDescription":"74LS28PC is an active NOR gate in bulk package.

For a direct 2-input NOR replacement, another 74LS-series quad NOR gate such as the 74LS02 (quad 2-input NOR) is a closer match in logic function and through-hole package."},{"question":"Can 74LS28PC replace 74LS02PC?","answer":"Both are quad 2-input NOR gates from the 74LS family. The 74LS28PC and 74LS02PC are functionally equivalent in logic, but pinouts differ — verify the pin configuration from the respective datasheets before substitution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/74LS28PC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/74LS28PC when reusing this data.
