The 72V06 is a 16K x 9 dual-port First-In, First-Out (FIFO) that operates at Vcc between 3.0V and 3.6V. The device will load and empty data on a first-in/first-out basis. It uses Full and Empty flags to prevent data overflow and underflow. And, it has a Retransmit (RT) capability that allows for reset of the read pointer to its initial position when RT is pulsed LOW. The 72V06 is designed for applications requiring asynchronous and simultaneous read/writes in multiprocessing and rate buffer applications.
