DESCRIPTION:

IDT72021/031/041s are high-speed, low-power, dual-port

memory devices commonly known as FIFOs (First-In/First-

Out). 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, (

AEF

) to monitor data overflow and underflow. Output Enable

(

) is provided to control the flow of data through the output

port. Additional key features are Write (

), Read (

), Retrans-

mit (

), First Load (

), Expansion In (

) and Expansion Out

(

). The IDT72021/031/041s are designed for those appli-

cations requiring data control flags and Output Enable (

) 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.
