That 10 ns figure is the time from read-enable assertion to valid data on the output bus — it sets the minimum cycle time for back-to-back reads and determines whether this FIFO can keep pace with a 50 MHz system clock without wait states. The CY7C425-10JXCT is listed as obsolete. For a production BOM, this means new designs should avoid it; existing builds will need to source from surplus or broker channels. The 32-PLCC footprint is common across the CY7C42x family, so a pin-compatible drop-in from the same series may be available — verify the exact speed grade and depth against your timing and buffer requirements. Because the CY7C425-10JXCT is obsolete, it is not available through the standard factory or authorized-distributor channel. Given the age of the part, pay close attention to date-code consistency and package marking — a clean laser etch and uniform plating on the J-leads are good signs of genuine Cypress inventory.","metaTitle":"Cypress CY7C425-10JXCT 9K Async FIFO, 10 ns Access","metaDescription":"Cypress CY7C425-10JXCT asynchronous FIFO, 9K (1K x 9), 10 ns access, 50 MHz data rate.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"CY7C","Package":"Tape & Reel (TR)","Function":"Asynchronous","Data Rate":"50MHz","Access Time":"10ns","Memory Size":"9K (1K x 9)","FWFT Support":"No","Mounting Type":"Surface Mount","Expansion Type":"Depth, Width","Package / Case":"32-LCC (J-Lead)","Product Status":"Obsolete","Bus Directional":"Uni-Directional","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5 V ~ 5.5 V","Base Product Number":"7C425","Operating Temperature":"0°C ~ 70°C","Retransmit Capability":"Yes","Current - Supply (Max)":"85mA","Supplier Device Package":"32-PLCC (11.43x13.97)","Programmable Flags Support":"No"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7b90e213fc80b06c2b8de53f062c1544.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C425-10JXCT obsolete?","answer":"Yes, the CY7C425-10JXCT is listed as obsolete.
