Data can be written into and read from the memory at independent rates. The order of information stored and ex- tracted does not change, but the rate of data entering the FIFO might be different than the rate leaving the FIFO. Unlike a Static RAM, no address information is required because the read and write pointers advance sequentially. The IDT72021/ 031/041s can perform asynchronous and simultaneous read and write operations. There are four status flags, ( HF, FF, EF, AEF) to monitor data overflow and underflow. Output Enable ( OE) is provided to control the flow of data through the output port. Additional key features are Write ( W), Read (R), Retrans- mit ( RT), First Load (FL), Expansion In (XI) and Expansion Out ( XO). The IDT72021/031/041s are designed for those appli- cations requiring data control flags and Output Enable ( OE) in multiprocessing and rate buffer applications. The IDT72021/031/041s are fabricated using IDT’s CMOS technology. Military grade product is manufactured in compli- ance with the latest version of MIL-STD-883, Class B, for high reliability systems.
