Texas Instruments TMS426409A-50DJ is a 16 Mbit EDO DRAM with a memory organization of 4M x 4. This device operates with a fast page mode access featuring Extended Data Out (EDO) capabilities, achieving a maximum access time of 50ns. It utilizes CMOS technology and supports RAS-only, CAS-before-RAS, and hidden refresh modes, with 4096 refresh cycles required. The component is housed in a 24-lead PDSO (JEDEC R-PDSO-J24) package with a terminal pitch of 1.27mm, designed for surface mounting. Operating within a temperature range of 0°C to 70°C, it requires a supply voltage between 3.0V and 3.6V, with a nominal of 3.3V. The TMS426409A-50DJ finds application in various computing and embedded systems requiring high-speed data buffering.
