                                                SN74ACT7804-40DL Overview
FIFO memory chip is included in the 56-BSSOP (0.295, 7.50mm Width) package.In terms of packaging, it comes in Tube cases.The FIFO chips have a memory of 9K 512 x 18  that can be used to store applications and data.It is recommended that the temperature be kept at 0°C~70°C to ensure reliable operation.Mounting type Surface Mount is assigned to the FIFO memory.A supply voltage of 4.5V~5.5V is required for its operation.The 74ACT series is represented by this memory logic.A Surface Mount mounting method is recommended.The 74ACT7804 family contains this item.When the supply voltage is 5V , high efficiency is possible.FIFO means contains 56  terminations.The operation pins are 56  pins.There is a maximum current requirement of 400μA for its operation.When the supply voltage is set to 5V , the FIFO's maximum efficiency is achieved.A self-contained gadget is contained within FIFOs .In this part, the memory type is OTHER FIFO .It is normal for a component to be equipped with 5V  power supplies.Using 2 circuits gives FIFO memory chip enhanced flexibility.
