FIFO memory chip is contained in the 144-QFP package.Bulk case is used for packaging.It is possible to store data and applications on the FIFO chips as they have 72K 2K x 36 in their memory.To ensure reliable operation, the temperature should be regulated to 0°C~70°C .There is Surface Mount  mounting type for this FIFO memory.High efficiency is possible with a supply voltage of 5V .The number of terminations in FIFO means is 144 .It is also possible to generate RETRANSMIT; PARITY GENERATOR/CHECKER; MAILBOX using this FIFO memory.It is set to 5.5V  volts for the FIFO memory IC's maximum supply voltage.Ideally, the supply voltage (Vsup) should stay above 4.5V .
