For a synchronous interface, the read-enable-to-data-valid window must accommodate this delay plus the setup time of the receiving device. ## Active production, RoHS non-compliant The part is RoHS non-compliant, which means it uses a lead-bearing solder finish (typically SnPb) rather than a lead-free alternative. For BOMs that require RoHS exemption 7(c)-I (lead in electronic components), this part qualifies. For fully RoHS-compliant assemblies, a lead-free equivalent would need a different order code. ## Bulk packaging — tray or tube The SN74ACT7811-18FNR ships in Bulk packaging — typically anti-static tubes or trays, not tape-and-reel. This suits low-to-moderate volume production or prototype runs where reel feeders are not needed.","metaTitle":"SN74ACT7811-18FNR FIFO, 1Kx18, 18 ns, Synchronous, TI","metaDescription":"Texas Instruments SN74ACT7811-18FNR synchronous FIFO, 1Kx18 depth, 18 ns access.
