The 45 mA maximum supply current is a reasonable budget for a 5 V FIFO running at this speed; a 3.3 V-only system would need a level translator or a different FIFO family. ## 68-PLCC footprint — hand-solderable but board-hungry The 68-PLCC (24.23 x 24.23 mm) J-lead package is one of the larger PLCC footprints. ## Obsolete — no official successor on record The CY7C4245-15JXC is listed as Obsolete.
