The SN74V215, SN74V225, SN74V235, and SN74V245 are very high-speed, low-power CMOS clocked first-in first-out (FIFO) memories. They support clock frequencies up to 133 MHz and have read-access times as fast as 5 ns. These DSP-Sync™ FIFO memories feature read and write controls for use in applications such as DSP-to-processor communication, DSP-to-analog front end (AFE) buffering, network, video, and data communications.

These are synchronous FIFOs, which means each port employs a synchronous interface. All data transfers through a port are gated to the low-to-high transition of a continuous (free-running) port clock by enable signals. The continuous clocks for each port are independent of one another and can be asynchronous or coincident.
