72V51253

4Q x18 2M Multi-Queue, 3.3V

The 72V51253 multi-queue flow-control device is a single chip within which between 1 and 4 discrete FIFO queues can be setup. All queues within the device have common data input bus, (write port) and a common data output bus, (read port). Data written into the write port is directed to a respective queue via an internal de-multiplex operation, addressed by the user. Data read from the read port is accessed from a respective queue via an internal multiplex operation, addressed by the user.

Features
