The Texas Instruments TMS426809A-70DGC is a 16 Mbit EDO DRAM organized as 2M words by 8 bits. This CMOS component offers a maximum access time of 70 ns, supporting fast page mode with EDO for enhanced performance. It features RAS-only, CAS-before-RAS, and hidden refresh cycles for efficient data retention, with 4096 refresh cycles. The device operates asynchronously with a nominal supply voltage of 3.3V, ranging from 3.0V to 3.6V. Housed in a 28-lead TSOP2 (R-PDSO-G28) surface-mount package, it is suitable for applications in consumer electronics, industrial automation, and telecommunications equipment requiring high-speed memory solutions. The component has 3-state output characteristics and is constructed with plastic/epoxy package body material.
