The Texas Instruments TMS4464-20NL is a Page Mode DRAM with a memory organization of 64K x 4 bits, providing a total density of 262,144 bits. Featuring an asynchronous operating mode and an access time of 200 ns, this NMOS technology memory component utilizes page mode operation to enhance data transfer efficiency. It supports RAS-only/CAS-before-RAS refresh cycles and offers a common I/O type with 3-state output characteristics. The component is housed in an 18-lead PDIP package (R-PDIP-T18) with a terminal pitch of 2.54 mm, designed for through-hole mounting. Operating within a temperature range of 0°C to 70°C and a supply voltage of 4.5V to 5.5V, the TMS4464-20NL is suitable for applications in industrial control and legacy computing systems.
