The Texas Instruments SMJ4256-12JDS is a 256K x 1 bit page mode Dynamic Random-Access Memory (DRAM) IC. This NMOS device offers a maximum access time of 120ns and operates asynchronously. Key features include support for RAS-only, CAS-before-RAS, and hidden refresh modes, along with separate I/O capabilities. The SMJ4256 series component is housed in a 16-lead Ceramic Dual-In-Line Package (CDIP) with through-hole mounting. It operates within a supply voltage range of 4.75V to 5.25V and a wide temperature range of -55°C to 110°C. Designed for demanding applications, this component finds utility in industrial, military, and aerospace sectors requiring robust memory solutions.
