Description
The IDT72205LB/72215LB/72225LB/72235LB/72245LB are very high speed, low-power First-In, First-Out (FIFO) memories with clocked read and
write controls.These FIFOs are applicable for a wide variety of data buffering needs, such as optical disk controllers, Local Area Networks (LANs), and interprocessor communication.These FIFOs have 18-bit input and output ports.The input port is controlled by a free-running clock (WCLK), and an input enable pin (WEN).Data is read into the synchronous FIFO.
