256Kx16 video DRAM with 60 ns access
The Texas Instruments TMS55160-60DGH is a 256Kx16 video DRAM organized as 262144 words by 16 bits, with a 60 ns access time. It comes in a PDSO64 package and is supplied in Bulk.
Active production, RoHS non-compliant
The TMS55160-60DGH is RoHS non-compliant — it does not meet the EU Restriction of Hazardous Substances directive. This is typical for legacy memory devices that use lead-bearing solder balls or internal die-attach materials exempt under certain categories.
Sourcing and compliance reality
Because the part is active but RoHS non-compliant, it sits in a narrow sourcing band: authorized distribution stocks it for legacy designs that require the non-RoHS variant, while the independent channel supplies it for repair and long-life industrial equipment that cannot migrate to a RoHS-compliant replacement. No pin-compatible second source or direct successor is recorded for this exact order code. The 256Kx16 video DRAM footprint is specific to the PDSO64 package and the 60 ns speed grade — a parametric substitute would require a board spin if the package or timing changes.
