                                                72615L50J8 Overview
The 68-LCC (J-Lead) package contains FIFO memory chip.In the shape of a Tape & Reel (TR) , it's packaged.It is possible to store data and applications on the FIFO chips as they have 18K 512 x 18 x 2 in their memory.It is recommended that the temperature be regulated to 0°C~70°C to ensure reliable operation.The mounting type of the FIFO memory is Surface Mount .A voltage supply of 4.5V~5.5V is needed to operate it.It is a member of the 7200 series .There is a maximum operating current of 230mA in memory IC's supply.I believe it belongs to the 72615 family of numbers.
