The Texas Instruments TMS55166-60DGH is a Video DRAM organized as 256Kx16 bits, with a 60 ns access time in a PDSO64 package. This part sits in the Analog & Data Acquisition category, reflecting its role in video memory subsystems where fast random access and high bandwidth are required.
Housed in a PDSO64 (Plastic Dual Small Outline) package supplied in Bulk, the TMS55166-60DGH demands a standard SOIC-64 footprint on the PCB.
Note that this device is RoHS non-compliant, so it is not suitable for assemblies requiring lead-free solder processes unless an exemption applies.
