Texas Instruments TMS4461 series Video DRAM, part number TMS4461-15NL, is a 65,536 x 4 bit memory device fabricated using NMOS technology. This component offers a 150ns maximum access time and operates asynchronously. Key features include RAS ONLY, CAS BEFORE RAS, and HIDDEN REFRESH modes, along with a 256 x 4 SAM port for enhanced functionality. The TMS4461-15NL is housed in a 24-pin PDIP package (R-PDIP-T24) with a 2.54mm terminal pitch, suitable for through-hole mounting. It supports a single 5V supply voltage (4.5V to 5.5V) and operates within a temperature range of 0°C to 70°C. This Video DRAM is commonly utilized in display systems and graphics controllers.
