DESCRIPTION:
The IDT7203/7204/7205/7206/7207/7208 are dual-port memory buffers
with internal pointers that load and empty data on a first-in/first-out basis. The
device uses Full and Empty flags to prevent data overflow and underflow and

available in the single device and width expansion modes.
These FIFOs are fabricated using IDT’s high-speed CMOS technology.
They are designed for applications requiring asynchronous and simultaneous
read/writes in multiprocessing, rate buffering and other applications.
