At 20 ns, the part supports a 50 MHz bus clock with zero wait states — the tag data arrives before the next clock edge. If your system runs faster than 50 MHz, you will need to insert wait states or look at a faster SRAM. The 512x8 depth (512 tag entries, each 8 bits wide) is sized for moderate cache sizes — think 256 KB to 1 MB L2 caches with 32-byte or 64-byte lines.","metaTitle":"SN74ACT2150A-20NT Cache Tag SRAM, 512x8, 20 ns","metaDescription":"TI SN74ACT2150A-20NT cache tag SRAM, 512x8 organization, 20 ns access time.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"series":"*","has_mpn":"74ACT2150","package_type":"Bulk","product_status":"Active","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$16.89","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9d29e4b2ebad4e795decac05ecc15d02.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I find the datasheet for SN74ACT2150A-20NT?","answer":"The datasheet is available from Texas Instruments and through our distributor portal.
