                                                SN74ACT7803-15DL Overview
56-BSSOP (0.295, 7.50mm Width)  is the package in which FIFO memory chip is contained.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.Keeping the temperature at 0°C~70°C will ensure reliable operation.There is a mounting type of Surface Mount on the FIFO memory.Operating voltage is 4.5V~5.5V .The 74ACT series includes this memory logic.It is pointing in the direction of Surface Mount .The 74ACT7803 family of integers consists of this type.When the supply voltage is 5V , high efficiency is possible.I found that it has 56 terminations in FIFO means.Operation pins are 56 .Its maximum operating current is 400μA .When setting the supply voltage to 5V , you will achieve FIFO's maximum efficiency.A self-contained gadget is contained in FIFOs .It has a OTHER FIFO memory type IC.Despite a frequency of 67MHz , it is capable of maintaining good accuracy.Components normally possess 5V  power supplies.Using 2 circuits gives FIFO memory chip enhanced flexibility.
