72V285数据手册集成电路（IC）的FIFO存储器规格书PDF

描述 Description

The 72V285 is an 64K x 18 SuperSync FIFO memory with clocked read and write controls. It's a functionally compatible version of the 72285 designed to run off a 3.3V supply for very low power consumption. The Frequency Select pin (FS) has been removed, thus it is no longer necessary to select which of the two clock inputs, RCLK or WCLK, is running at the higher frequency. SuperSync FIFOs are particularly appropriate for networking, video, telecommunications, data communications and other applications that need to buffer large amounts of data.
