The Texas Instruments TMS427400-70DGB is a 16 Megabit (4M x 4) Fast Page Mode DRAM operating at 70ns access time. This CMOS component features a 4-bit data width and supports multiple refresh modes including RAS-only, CAS-before-RAS, and hidden refresh, enabling efficient data retention with 2048 refresh cycles. Designed for surface mounting, it is housed in a 24-lead TSOP2 package with a 1.27mm pitch. Operating within a supply voltage range of 3.0V to 3.6V (nominal 3.3V), this device is suitable for applications requiring high-speed memory solutions in sectors such as industrial automation, consumer electronics, and telecommunications. The asynchronous operating mode and CMOS technology ensure reliable performance for demanding system designs.
