HB56A264EJ Series
2,097,152-word 64-bit High Density Dynamic Module
Under development Rev. Oct. 1994
HB56A264EJ belongs byte DIMM (Dual In-line Memory Module) family been developed optimized main memory solution Byte processor applications. HB56A264EJ dynamic module, mounted pieces 16-Mbit DRAM (HM5117800BJ) sealed package pieces 16-bit BiCMOS line driver (74ABT16244ADGG) sealed TSSOP package. outline HB56A264EJ 168-pin socket type package (dual lead out). Therefore, HB56A264EJ makes high density mounting possible without surface mount technology. HB56A264EJ provides common data inputs outputs. Decoupling capacitors mounted beneath each module board.
