                                                QS7201-25SO Overview
You'll find it packaged in the shape of a Bulk .The FIFO chips have a memory of 4.5K 512 x 9  that can be used to store applications and data.Keeping the temperature at 0°C~70°C will ensure reliable operation.This FIFO products can operate at a maximum operating supply current of 60mA .When the supply voltage is 5V , high efficiency is possible.As a result of this, FIFO means contains 28  terminations.Additionally, RETRANSMIT can be generated with this FIFO memory.As a result, Vsup is set at  5.5V  (FIFO memory IC's maximum voltage supply).In order to ensure normal operation, the supply voltage (Vsup) should be kept above 4.5V .
