The Texas Instruments TMS427809A-70DGC is a 16 Megabit (2M x 8) EDO DRAM, operating with a maximum access time of 70ns. This CMOS component utilizes Fast Page Mode with Extended Data Out (EDO) for enhanced performance, supporting RAS-only, CAS-before-RAS, and hidden refresh cycles. It features common I/O and 3-state outputs within a 28-lead, 1.27mm pitch TSOP II package (R-PDSO-G28) with a body measuring 10.16mm x 18.41mm. Operating from a 3.0V to 3.6V supply, this surface-mount device is suitable for applications in industrial automation, consumer electronics, and networking equipment. The component has a standby current of 1mA and a maximum supply current of 90mA.
