DESCRIPTION:
The IDT72413 is a 64 x 5, high-speed First-In/First-Out
(FIFO) that loads and empties data on a first-in-first-out basis.
It is expandable in bit width. All speed versions are cascad-
able in depth.
The FIFO has a Half-Full Flag, which signals when it has 32
or more words in memory. The Almost-Full/Empty Flag is
active when there are 56 or more words in memory or when
there are 8 or less words in memory.
The IDT72413 is pin and functionally compatible to the
MMI67413. It operates at a shift rate of 45MHz. This makes it
ideal for use in high-speed data buffering applications. The
IDT72413 can be used as a rate buffer, between two digital
systems of varying data rates, in high-speed tape drivers, hard
disk controllers, data communications controllers and
graphics controllers.
The IDT72413 is fabricated using IDTs high-performance
CMOS process. This process maintains the speed and high
output drive capability of TTL circuits in low-power CMOS.
Military grade product is manufactured in compliance with
the latest revision of MIL-STD-883, Class B.
