FEATURES:

DESCRIPTION:

•

The IDT72V81 is equivalent to two IDT72V01 - 512 x 9 FIFOs

The IDT72V82 is equivalent to two IDT72V02 - 1,024 x 9 FIFOs

The IDT72V83 is equivalent to two IDT72V03 - 2,048 x 9 FIFOs

The IDT72V84 is equivalent to two IDT72V04 - 4,096 x 9 FIFOs

The IDT72V85 is equivalent to two IDT72V05 - 8,192 x 9 FIFOs

word size and depth.

— Active: 330 mW (max.)

— Power-down: 18 mW (max.)

Ultra high speed—15 ns access time

Asynchronous and simultaneous read and write

Offers optimal combination of data capacity, small foot print

and functional flexibility

The reads and writes are internally sequential through the use of ring

pointers,withnoaddressinformationrequiredtoloadandunloaddata. Data

The devices utilize a 9-bit wide data array to allow for control and parity
