It buffers and drives heavily loaded backplane or memory-array lines. ## Active, but watch the RoHS flag The catch is the RoHS compliance status: this variant is listed as RoHS non-compliant. That means it uses lead-bearing solder terminations and is not acceptable for new designs targeting RoHS-required markets (EU, California, etc.) unless a specific exemption applies. For legacy repair, retrofit, or military/aerospace builds that are exempt or explicitly allow tin-lead, this is exactly the part you want — the lead finish is more robust against tin whiskers in high-reliability environments. ## Where it sits in the cycle The active status indicates TI continues to run AS-series wafers. Demand is steady from legacy industrial and defense programs.","metaTitle":"SN74AS240N Bus Driver, AS Series, Active","metaDescription":"Texas Instruments SN74AS240N bus driver, AS series.

It covers the electrical characteristics, switching waveforms, and application information for the AS240 octal buffer/line driver. The datasheet is the authoritative source for the device's operating conditions and timing parameters."},{"question":"How does SN74AS240N compare to 74LS240?","answer":"The SN74AS240N is the higher-performance sibling in the Advanced Schottky family. Compared to the 74LS240, the AS version offers significantly faster propagation delays (typical in the 5-7 ns range versus 12-18 ns for LS) and higher output drive current (64 mA sink versus 24 mA for LS). The trade-off is higher supply current. Both are 5 V, inverting three-state octal buffers with the same pinout, so they are drop-in compatible on the board. The AS part is the choice when the bus timing budget is tight or the capacitive load is high."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74AS240N","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74AS240N when reusing this data.
